Logic Pro X LPX 10.4 not reading markers on wav file bounced in Logic

- bounced a 24-bit, 44.1k wav file
- imported that bounced file into a new Logic session
- previously, Logic would recognize a wav file has tempo and marker info, but since I updated from OS X 10.10 to MacOS 10.12.6, and then updated Logic to 10.4, this behaviour doesn't occur

Anyone out there know what this might be about? Is this a bug? Is there a default setting in Logic I have to re-toggle to get the behaviour back?
