Audio waves in mkv archives

Greetings.
I recently upgraded to davinci resolve 17. My problem is that I import mkv videos and I can't see the audio waves to edit them. In the mkv audio track I can only see fragments of the wave. The track in mp3 can be seen in a continuous wave without any type of cut. What is this about?
Thank you

This was improved in 17.2.1

It's the version that I have installed. In the last version I had installed (15), this was not a problem, it's strange. Thank you.
