Advice on how to create a feature where the player selects options, then selects one option to be active

Hello helpful people!

I made a Dex Barb subclass that selects from a list of possible stances (basically fighting styles) and then when they rage they activate one of those stances. They can only activate one of the stances they selected at character creation. There are 8 total stances, and they select 2 at 3rd level, and then activate only 1 at a time when raging. Some of the stances have stat bonuses (e.g. +2 to attack roles) so I want those to update character sheet when selected.

So I made it and it basically works - which is cool, but the way I did now makes the subclass description page look weird. I made a feature called Amazon Warrior Stance with all 8 stances that they select during character creation. I hid this feature on the character sheet. Then I made another feature that is called Activate Warrior Stance where they can select one of the prerequisite options they selected at character creation. I hid this on the character builder. The idea is that at character creation they choose which stance options they want. Then on the character sheet they activate one of these. Maybe I did this wrong, or suboptimally. 

Anyway - for some reason the Activate Warrior Stance is showing on the Subclass description page. Everything else works fine on the character sheet. Any ideas?
