Hi,

I manually added repository packman on Leap 15.0 (by URL). I then tried to 
change priority from 99 to 98. Yast warned:

     Repository 'Ext_Packman' is managed by service".
     Your manual changes might be reset by the next service refresh!

What on earth is that!?

Note: The string «service".», I guess that '"' was '"', but I can not 
actually make it out what it was, too tiny.
