Corrupted Audio Region

[Johnbee58]

Since I downloaded and installed the latest update (2021-9) I'm starting to see an error message I haven't seen since I've been using Cakewalk by Bandlab (3.5 years).  If I convert a MIDI file to an audio (WAV) file and open it up in a new project I sometimes (not always) get "A corrupt audio region was detected and padded with silence" when I launch the project with the converted MIDI to audio file. But the funny thing is, the audio file doesn't seem corrupted!  It plays fine, but I get the error message every time I open the project. This used to happen quite frequently in Sonar X3 but this is the first I've seen it since CbB and it also didn't happen before the last update when the Export feature was changed.  Perhaps I'm not using something in the new Export feature correctly?  I'm using all default settings except I'm transferring to a folder other than the default. 

Maybe a bug that needs fixin'?

Thanks
