Sublime Text 3 | Build with Hotkey "CMD + B" doesn't work anymore

Hey guys,

hope this is the right section for my question.

I had to format my mac and install everything from scratch.
Now I have the problem that appeared to me a few months ago.
I can’t run my project trough sublime with the Hotkey CMD + B anymore.
I have to use CMD + fn + F10.
A few months ago I’ve found a solution for that in this forums (I think), but I can’t find it now again.

Do somebody know how to change the hotkey back to CMB + B ?

Thank you very much in advance!

Has no one an idea for that?
