Changes between 2 engineering stations

Hello,

I am currently struggling with an issue involving my two engineering stations.
I have Engineering Station A, which contains a project in state A-1. I transferred project A-1 to Engineering Station B (both stations are running ProviewR version 5.9-2). On Station B, I made some modifications to A-1, resulting in project state A-2.
I then transferred project A-2 back to Station A and replaced the old state A-1 with the updated A-2 version. However, I am now experiencing a problem: the changes I made in A-2 do not seem to work on Station A.
For example, I added an OR block to my PLC program. But when the OR block receives inputs 1 and 0, it outputs 0, even though nothing is inverted and the logic should output 1.
Additionally, another PLC object created in A-2 shows the following error message only when opened on Station A:
 

Does anyone know what might be causing this behavior or how to correctly synchronize projects between stations?

Any help is appreciated.
