Shift to mark more than one note slur bug?

Recently updated to latest Dorico version, 6.2.30 version.

Its a bit hard to explain in writing, but when you have a bar with a legato slur and I want to delete more notes that is under the slur. I click the first one, then shift click right or left on the keyboard to mark the other notes, however now (I’m pretty sure it didn’t behaved like this before) it marks the slur also. Is this a recent bug or a feauture? It is very frustrating when most of my workflow is with keyboard and not clicking with mouse, but now I have to deselect the slur after trying to remove something inside it.
