Tap tempo reports faster tempo (fixed)

I use shift+space to calculate tempo of a song… I tested it with two songs which I know the tempo and I get faster tempos.
The song tempo is 84 and I get 91.
The song tempo is 118 and I get 130.

What I amb doing wrong?

Thanks for your kind help.

Edit:
I found the problem… The audio interface is set to 48kHz and the project is 44kHz.
