"Field device data has changed" dialog appears when logging in

What happens?
Although no parameters were changed, the parameter comparison dialog appears when logging in to the controller. Under "Details", no differences can be seen.
Example:

When does this behaviour occur?
The behaviour occurs when the PLC Designer is used to transfer a PLC project to the controller. After this, log out and log in is performed with the PLC Designer.
The behaviour may occur with the following parameters:
- Position controller: Output signal limitation (0x2982 | 0x3182)
- Speed offset (0x60B1 | 0x68B1)
- Speed limitation: Upper speed limit (0x2946:1 | 0x3146:1)
- Speed limitation: Lower speed limit (0x2946:2 | 0x3146:2)
 
Which products are affected?
PLC Designer from version V3.12
 
Short-term measures:
Ignore the message if the values indicated under "Details" are identical.
