Overview Error when creating RTU Object in MODBUS EXPLORER

When I want to create an Device via. "Modbus Explorer" it works flawless when I choose Modbus TCP. When I try to do the same with Modbus RTU, I get the following window. Only explenation window about config settings, but no Config setting available. Seems to me like a bug. Is there a fix for it ?
In Matlab I get this codes as feedback:
Warning: Error executing listener callback for PostSet event on UserAddNonEnumDeviceStartPage dynamic property in object of matlabshared.mediator.internal.Mediator class:

Tried this on different Matlab versions R2024a,R2022b,R2020a. Laptop with Win 11
Any fix for this available, if not how to properly report bugs.When I want to create an Device via. "Modbus Explorer" it works flawless when I choose Modbus TCP.
