Symbols are displayed under "Project styles" group instead of "Default" in symbol editor

[DelazJ]

What is the bug or the crash?

In style manager, I have symbols in the "Default" group. However, while editing a symbol, they are listed under "Project styles" group in the symbol editor dialog instead of "Default".

Steps to reproduce the issue

The style manager dialog in 3.35 shows that the symbols are indeed from the default group

I do have this issue in 3.38.2 on a Windows machine

Likely an upstream (qt) issue which has been resolved in newer Qt builds
