[RPG] Overlapping Proficiencies From Leveling

archetypebackgrounddnd-5ednd-beyondproficiency

In my game I'm a Rogue with the Entertainer background. Leveled up enough to pick a subclass and decided on Mastermind for the teamwork possibilities. The subclass gives Disguise Kit proficiency, something I already had from my background. If I do the level up in Beyond it insists I pick a new tool proficiency for my background. But I'm not making a new character, I'm leveling up an existing one. How should I handle this?

So far I've been treating it as a glitch with Beyond (it sees characters as 'new' even if they have experience being tallied) and ignoring it's suggestion as anything from levels prior to the current one are effectively set in stone barring DM caveat. Still, would be nice to have a more concrete way of dealing with this than a hand wave.

As the Background section about Proficiencies (PHB p.125) says,

If a character would gain the same proficiency from two different sources, he or she can choose a different proficiency of the same kind (skill or tool) instead.

I believe the way they've implemented this in Beyond is the new class feature becomes the source for your Disguise Kit proficiency, and the one from your background changes to let you pick a different tool proficiency in lieu of your Disguise Kit.

I think it's working as intended, it just might look a little strange.
