Keyboard hotkey does a different thing than it is supposed to

I upgraded my Ubuntu to a newer version and thus I LibreOffice Writer was updated as well.
I had previously customised ctrl+alt+f to add a footnote. It still is according to the hotkey settings. However they key combination now opens a path file->new. This is due to alt+f doing this function. Which however is not shown on the list of hotkey functions. How do I fix this issue?
