VScode rotates multiple formatter

I use the uncrustify extension from LaurentTreguier which worked as intented. But now vscode started to rotate formatter when i press Ctrl+Shift+I.

Means one time uncrustify is executed and the next time some other formatter, which i don't know. I also have the C/C++ extension from MS installed.

And only configured uncrustify for the workspace.

How can i set the command to only use uncrustify? Or how can see which other formatter is used. Is there a other way besides looking the debbuging terminal for uncrustify to determine which code formatter was executed?
