Conversion of the CanOpen configuration causes compilation errors

Which products are affected?
PLC Designer from V3.5

What happens?
While compiling the PLC project, the following error message appears in the message window:
[ERROR]: The referenced CANopenStack is not compatible with the current CANopen configuration version of the CANopen_Manager device

When does the problem occur?
When a PLC project (version 3.3.x or lower) is updated to the version (from 3.4 or higher), the project cannot be compiled correctly if at least one CAN bus in the PLC project is used with CanOpenManager and a device description of a device used is not installed (red question mark in the device tree).

Diagnostic options?
None

Short-term measures/recommendations?
? Install the missing device description of the device used (afterwards, no red question marks are visible anymore in the device tree)
? For every CanOpenManager used in the project, carry out the 'Update device' to the newest version.
Afterwards, the PLC project can be compiled correctly.

Evaluation
A PLC project cannot be compiled correctly if CAN device descriptions of the devices used in the project are missing after the update.
