You must still have air in the system, can you see air when you bleed the clutch?

You must have sufficient clearance between the pedal and master cylinder push rod. If there is insufficient clearance, the master cylinder piston would not return fully and prevent fluid from going into system to bleed the air out.

Perform the following and then bleed the system again.

CLUTCH PEDAL & CLUTCH PEDAL POSITION SWITCH ADJUSTMENT
NOTE:
• The clutch is self-adjusting to compensate for wear.
• If there is no clearance between the master cylinder piston and push rod, the release bearing is held against the diaphragm spring, which can result in clutch slippage or other clutch problems.

1. Loosen locknut (A), and back off the clutch switch (B) (or adjusting bolt) until it no longer touches the clutch pedal (C).

2. Loosen locknut (D), and turn the push rod (E) in or out to get the specified stroke (F) and height (G) at the clutch pedal.

? Clutch Pedal Stroke: 141-151 mm (5.6-5.9 in.)
? Clutch Pedal Height: 190 mm (7.5 in.)

3. Tighten locknut (D).

4. Turn the clutch switch (B) in until it contacts the clutch pedal (C).

5. Turn the clutch switch (B) in an additional 3/4 to 1 turn.

6. Tighten locknut (A).

7. Loosen locknut (H) and the clutch interlock switch (I).

8. Press the clutch pedal to the floor.

9. Release the clutch pedal 15-20 mm (0.59-0.79 in.) from the fully pressed position, and hold it there. Adjust the position of the clutch interlock switch (I) so that the engine will start with the clutch pedal in this position.

10. Tighten locknut (H).

I must still be drawing air in from a faulty master or slave, that is about all i can think it can be, if you have checked the pedal clearance.

If the master cylinder was not bench bled, it is not going to be easy to bleed it. Since air is still being pumped out, you would need to perform the bleeding again till no air is present. Try it with slow strokes of the pedal. Recheck the joints for leakages and if all fails, as mhpautos mentioned, it could be a faulty master cylinder.

New master cylinders are known to fail and if it was not bench bled, constant and prolonged pumping of the master cylinder can damage the seals.

Was bleeding procedures done correctly?

Recheck the master cylinder push rod adjustment. The push rod should be free without any resistance when pedal is not depressed.

How was the bleeding process performed?

Get a vynl tube and plug it into the slave cylinder bleeder and lift up the tube with bleeder opened. Top up the fluid in master cylinder and allow the fluid to flow down. Wait 30 minutes before you start bleeding. Before bleedig the system, try pushing the pedal a few tiems with slow strokes to get air out.

Don't forget to put the end of vyny tube in a container to prevent fluid from spilling.

Seems when air is in system, either you allow sufficient fluid into the system or you would need to pressurise the system to get the air out.
