DVR 17 "Select clips forward/backward on this track" bug?

Hello,

I'm quite sure this is a bug and I wondered if there's a place to report this or if I can assist with some logs/other to BMD

I have a specific timeline in my project behaving abnormally with the following shortcuts:
-Select clips forward/backward on this track (2)
-Select all clips forward/backward on this track (2)

When I press one of those shortcuts (4) the followings happen:
-The clip/s currently selected is unselected and nothing else happens (more common)
-The performed action is not according to the shortcut, e.g. instead of select forward -> selecting backward (less common)

Timeline settings are- 1920x1080 25 fps
I've tried:
-Replacing shortcuts key's -> issue remain on faulty timeline
-Testing on different timelines with different configuration -> no issue
-Creating and testing on a new timeline with the same configuration(1920x1080,25) -> no issue
-Copying all clips from faulty timeline to a new timeline -> no issue

DVR17.0B build 33

I used those shortcuts quite a bit recently in Studio 17b9 for Windows and didn't see any anomalies.

If it's only happening on one timeline...man I can't think of an explanation for that.
