2014 Core Rules Warlock Mystic Arcanums Missing

I have a level 19 Warlock using 2014 Core Rules and Xanathar's Guide to Everything.

I have a couple of issues in character sheet setup:

1) For Mystic Arcanum I should see both the 2014 Core Rules and the additional Spells I get from Xanathar's. However, I only see Xanathar's "extra" spells as the only spells. I had to enable the 2024 Core Rules to get closer matches to the 2014 materials, but it causes other issues.

2) At level 19, I have the option for Boon Feat, which is a 2024 core rule change but does not exist at all in 2014. This item stays even when I disable the 2024 rules.
