When branching them from Leap and (in the case of plasma5-SLE) openSUSE:Backports:SLE-15 they work fine, so it seems like they were removed from the repo by mistake.

There is a bug for this: bsc#1154410

Unfortunately, there is no official engineering support for Packagehub, so this may take a wee bit of time to get fixed.
