Missing Major Version for DocumentUnderstanding AI Center

Previously i do training on below Pakage major version 14 in pictures

But as I was working and upgrading other ML Packages (The above Pakage stays the same) I notice that the version 14 was no where to be found and now I can’t deploy the version 14.2 so I have to downgrade to 12.23 (Which is still in the list)

I already done training on different version but still wants to know why it’s not there anymore
