Why the front roof latches do not fully open?

Guys, I've just fixed a leak in the front top latch hydraulic cylinder, I've put the cylinder back in, but the latches do not fully open to allow the top to meet the windsheeld.

I don't think it's about the hydraulics (which work fine), even with a wrench I can not fully open the latches. (With the wrench I could open/close the latches easily prior to the cylinder replacement). So I must have put something together in a wrong way, any ideas? Here is the photo of the open latch when trying to close the roof, as you can see the hook of the latch rests on the bracket and does not go through, the roof does not meet the top of the windshield.




Here is the cylinder in the "pushed in" , latch closed position:



Any ideas of what went wrong? Thanks!!!!!!

FIXED. Two things went wrong:

1) The big black frame holding the cylinder should be aligned/positioned properly for both latches to fully open, if the frame is not centered properly, only one latch opens (moves out) and there is not enough room for both latches to clear the brackets. So mark the bracket position before removing, to avoid adjusting it later

2) I had the connector at the end of the piston shaft up-side-down, photo of the corrected installation is below:
