Weird issues with DLC and game overall(And Preorder)

So for context, I preordered the Deluxe Edition on my main profile, however I rarely use that account anymore Minecraft wise as my current main account is connected to a secondary Switch profile. I tried to link it so that account would be the one to claim the Pre-order bonus, unfortunately it didn't work and found out that’s related to Microsoft accounts linking to a singular Switch profile, not sure what could be done there, but the main issue is the game and DLC’s software.

It was mentioned in another report by someone the DLC doesn't exactly transfer across Switch profiles, not sure if that's on purpose or not, but from having log in issues I did purchase the DLC a second time specifically on that account, then when it fixed the DLC part at least, it still had a few other problems, so I purchased the initial game separately slightly after.

It “kinda” seemed to fix the log in issues but there's a problem I put in another report about that, however, when trying certain things, I ejected the Digital Game Card(and DLC) from the main account to try to fix the log in issues, and it asks to have it insert the game and DLC from the main account, despite the only difference being that it was bought as the Deluxe Edition and this was it bought separately and in a reverse order.

I don't know if the DLC thing is a bug or not and a part of that and how I purchased it is causing this, but after buying the game and DLC technically twice, part of it potentially for nothing, kinda want to know if there's anything specific I could do, or at least the log in and preorder issues.
