Changing Vendors On Update

Upon updating, is it common practice to change vendors when packman doesn’t reconcile with openSUSE? I was going to be patient and wait to see if it balanced as time goes on but if this is unnecessary then I’ll change vendors. Matters not to me. The following 20 packages are going to be upgraded: gstreamer-plugins-base libdca0 libgmic3 libgstallocators-1_0-0 libgstapp-1_0-0 libgstaudio-1_0-0 libgstfft-1_0-0 libgstgl-1_0-0 libgstpbutils-1_0-0 libgstriff-1_0-0 libgstrtp-1_0-0 libgstrtsp-1_0-0 …

These two packages got removed from packman and need to be switched back to openSUSE repo.
