Blocks Getting Re-Numbered In Renoise 2.8

Even though I have “keep sequence sorted” unchecked - something weird is going on.

I have only created ~25 blocks but now the timeline is numbered up to 43

One thing I saw - I added some track automation to a block and it automatically added (and created new identities for) a whole bunch of subsequent blocks, but I really didn’t want it to do this.

I no longer have all the blocks with one theme in the 10s and all the blocks with another theme in the 20s - how one earth do you have any kind of workflow with these re-numbering feature enabled? I just find it confusing.

I thought I had it worked out when I disabled “keep sequence sorted” but there must be some other features that hopefully I can disable somewhere …
