KRunner keeps forgetting recent commands

I love KRunner and use it many times a day. I have a number of scripts I wrote to accomplish tasks and have always relied on KRunner’s recent files functionality to find them: after I finish a script, I launch it with Dolphin and thereafter I can launch the same script with a few keystrokes using Krunner. Or so it used to be. Some time in the last several weeks, KRunner frequently seems to forget all the recents forcing me to launch Dolphin, navigate to the right scripts folder, and double-click the script. That will fix things for a day or three, and then KRunner gets amnesia again. I’ve gone through the (sparse) configuration options, and cannot find anything that would seem to be helpful.

Online searches haven’t revealed anyone else with the same problem, which makes me think it’s something I messed up and not a bug.

Anyone have an idea what I’m doing wrong?

Invoking “Clear History…” from KRunner Settings seems to have fixed the problem.
