MCU plugin doesn't let me change the SDK version

I'm trying to change the SDK from Z:\sdks\TVII-GraphicsDriver-V1.2.0 to Z:\sdks\TVII-GraphicsDriver-V2e.1.0, however the UI says "A kit for the selected target and SDK version already exists".

It says this no matter what I enter in the "Graphics Driver for Traveo II Cluster Series" field.

If I then go to configure a project for the Traveo II 6M I get an error about wrong SDK version:

Instead, I have to go to the "Build Settings" and change the SDK version manually:

So it seems the text that says "A kit for the selected target and SDK version already exists" is wrong. Either the bug should be fixed so that it is possible to change the SDK version, or the text should be updated to say that if you want to change the SDK version you have to first delete the existing kit.
