I’m trying to make a homebrew Minotaur specific feat for my friends campaign, however even though I own the Minotaur on D&DB, it’s not letting me select it as an option for the prerequisite in the homebrew Feat creator. Has anyone else had an issue like this?

Only the races who got racial feats in Xanathar’s are selectable as the prereq for a racial feat.

That doesn’t make sense, it allows me to pick Aaracokra, Genasi, Aasimar, Changeling, and Gith for the prerequisite options, and those are ones I own. 

It looks like it's not including the races from Magic the Gathering content (Theros & Ravnica), as well as races from newer content like Witchlight. It probably also excludes Non-Core content like Locathah and Grung, but I don't own those so wouldn't be able to check.

It might only be all of the core content that was out when Xanathar’s dropped but nothing non-core and nothing since then.
