Audio files corrupt after raise sample rate of projects

Hi,

I was forced to raise sample rate in couple projects from 44 to 48 in Cubase 10 on Mac. After converting those some parts of audio files was sound corrupted in project only. There are coming some digital distortion sound for random clips.
While (source) audio files in pool sounds good and properly.

How can I fix it?

Thanks!

Issue was solved with regular processing for broken clips in pool only. Just normalized it, for example.
