Got a very strange and scary issue:  CA fiduciary return form 541 for 2022.

We have one central server and 7 workstations.    My staff finished the said return.   I reviewed and made couple changes, specifically on CA PTE tax.     The changes I made only reflected on my workstation, the other workstations and server do not reflect this change.    My file directory is the network drive.    If I delete a number in this client file, the other workstations see the same but are not calculating the same way.     

Called Lacerte and they said perhaps workstations are not updated.   I know we did but waited till after hours and updated all workstations.   Still the same.   My workstation calculate the result differently than the other workstations.    I will call Lacerte again tomorrow.

Any ideas?
