Software updates in Plasma 5 gives me three identical simultaneous notifications if there's any files to update and it does that several times a day, about hourly. Check interval is default "daily" so shouldn't it give only one message per day? Any way to make it behave like that? I'm using openSUSE Tumbleweed, Plasma 5.4.2, Qt 5.5.1, Frameworks 5.15.0. Update checking and updating from command line (zypper) works without problems. I've added some repositories and locked some packages if that makes a difference.

This is not part of Plasma 5, but only openSUSE anf Fedora. I have seen this issue but I'm not sure what is causing it.
