The latches are fixed by 3 screws to hold them in place and is not adjustable. What you need to adjust is the door striker bolted onto the frame.
If they can be twisted with a screwdriver, it means the holding screws are not correctly torqued.
Loosen the holding bolts just enough to allow the striker to be moved and hold door as close to striker as possible.
Ensure the striker is in line the the slot of the latch on the door.
Adjust striker if necessary and tighten the holding bolts.
Close door and note if it is flush with body. If it is too far out, loosen the striker holding screws and tap the striker inwards, do not allow the striker to move upwards or downwards.
Retest closing and repeat adjustment till the door is correctly aligned.
