FFL instruction weird behaviour

Hi,

i have a logic:

XIC load_enaX ONS bitX FFL X array[0] arrayctr len pos

where X is from 1 to 12

it's a plasterboard monitoring system where i have 12 decks being merged onto one conveyor on the FIFO basis. But sometimes it happens that one deck is not loaded into the FIFO and it gets stuck eventually leading to production breakdown. I have diagnostic data which say that the bits load_enaX are being set properly every time, but the FFL does not push the number X into the FIFO. It happens irregularly every once in a while, say once per week, otherwise it's running just fine. Can there be the problem that the FFL does not like the one shot execution? Or is there any other info on the FFL that I am missing?

Thank you very much guys
