Mark of Healing origin feat not allowing the use of Intelligence for the Healing Touch spells

The Healing Touch part of Mark of Healing says:

Healing Touch. You always have the Cure Wounds spell prepared. You can cast it once without a spell slot, and you regain the ability to cast it in that way when you finish a Long Rest. You can also cast it using any spell slots you have of the appropriate level. Intelligence, Wisdom, or Charisma is your spellcasting ability for this spell (choose when you select this feat).

But I'm not able to select Intelligence for the spell casting ability, only Wisdom or Charisma.

Confirmed, also seeing Intelligence. Tested both in character options and manually added on sheet via Firefox.

It's missing Wisdom for me.

Realising it might be because i still have the (Broken) version on my character, but I can't seem to find a way to remove it and not have both versions.

Deleting it and adding it back does not fix it. I'm seeing a lot of people having this issue. I get the mark from the House Jorasco background selection, which fails to work. Adding the feat on it's own still does not work properly. The feat was working properly a few months ago but then stopped working properly.
