Players on teams but not in season draft

Hi. I'm playing UBR for 2k14 and I've added about 30 legends to the 2023 roster so far. Two of them don't appear in the fantasy draft when I play a season with the roster. I think they're both there on the right team when I play a season without a draft, but if I do a draft before the season, they disappear.

I've gone through the Players tab and the Teams tab in Red MC, and couldn't find anything amiss. I also tried trading the two players to another team within the roster, but they remained invisible in the draft. What am I missing? KG and Wilt are really important!!!
