Tempo detection

when I do tempo detection on a track which was recorded @ 48-24 and then attempt to insert a signature at the downbeat the program crashes. If the file is 44.1-16 it works… What am I doing wrong? The project is set up for 48-24.

Imac pro os 10.14.6


Could you attach the crash file (located in macOS Console utility, User Reports folder in it), please?
