I have recently created two Reddit threads that i'm going to link to because they contain all the information for these two bugs.

I'm not receiving the benefits of placing a Transmigration Beacon on a special node

Transmigration Beacon bandwidth cost does not scale correctly when dismantling the first beacon hacked.

If these are bugs, then it's a little worrying that they've been left unaddressed for so long.  They're a very large impediment when trying to play efficiently with UC.

Thank you

I just ran into the same issue (#2). Still not fixed, and judging by the lack of responses in this thread they see no need to.

Such a shame.

I now have a 20 BW cost beacon and a 50 BW cost beacon.

Last patch brought so many bugs, I think devs should revert all changes with the last DLC, or simply disable it and revert last patch. So sad, but I simply don't believe they will ever fix this game.
