weird trunk locking/unlocking issue

[omodos]

Hello all, got an odd issue, locked the car via the keyfob today, got back to car to put something in the back and used the button on the keyfob to unlock the rear only....the lock mechanism made the usual noise it does when disengaging.....but when I tried to lift it open it locked again....but didn't seem to lock fully as I could see the panel was not fully flush with the ther rest of the body bodywork and I could see the lights were on in the trunk

Tried a couple of times same issue, seems that when using the key fob to unlock just the upper rear it wont open...whereas if the car is already unlocked and I manually use the soft touch lift the trunk it disengages and also lifts open fine......

To be honest for the life of me cannot remember if using the key fob to open the trunk only actually fully pops open the rear or whether i had to press the 'button' on rear to release and lift the hatch.


any input much appreciated-I scanned other posts here and didnt see any that were the same as mine.....
