Not sure if this is a bug or just a weird disadvantage of SubD, but it will not let me delete adjacent edge loops (like loop #1 and loop #2 in the attached image). It will, however, let me delete a few loops simultaneously only if they are not adjacent (such like loop #1 and loop #3). Is there a fix for that?

i noticed a few times that deleting several loops simultaneously does not work while deleting them one by one does which looked like a bug to me at that point. not on a computer right now and i may be dreaming that up, did you try deleting them separately?
@Rhino_Bulgaria yep happens here too

I can delete them individually or if I delete multiple edge loops that are not adjacent to each other. Never had such an issue with any 3d modeling program that uses Catmull-Clark subdivision.

This gets me every now and then. I don’t remember how it was in T-Splines?
I think what is happening here and @pierrec can correct me if I’m talking BS… is by deleting those edges you are essentially removing all the definition for that entire face loop which would create a hole.
you can however, and this is a bit counterintuitive, accomplish this by selecting the two edge rings and run the stitch command which collapses the face instead of deleting it. Which does not create a hole.
remember in stitch you can decide where the edge rests at the end of the command, here I’m using the default which is averaged.
