Loop range re-snapping on its own, cubase 8.5.3


I installed a fresh Windows 10 system, updated my Cubase from 8.5.2 to 8.5.3 and now I’m experiencing a really strange issue (check the attachment).
When I select all clips and then apply any audio process to them via the menu (such as Remove DC offset), after the process has been applied, the loop range snaps by itself to a random, narrower value.
Is that something caused by the 8.5.3 update that I might have missed, some preference setting or something, or is it a bug?
The same issue sometimes happens even when I simply select all the clips in the project, but that’s not always reproducible like the first example.
Thank you
