Navigations keys and Chrome browser - anyone else have this issue?

The navigation keys are acting erratically. Up/down will work a few times but then do god knows what - end, home, beginning or end of the line. All the others are FUBARed from the start. I’ve
checked on other apps, including Edge, and don’t have the same problem. I’ve checked for updates for both Chrome and the keyboard and am up to date. I even installed & reinstalled Chrome. Not the keyboard, though, because it’s not a major brand and I’m afraid of it not being recognized. Silly, maybe, but I’m confident it’s not a hardware issue. It’s an iClever BK10 bluetooth. And searching google and fora only shows problems with the keyboard not working altogether.

For what it’s worth, everything works in this box except up/down. I had the same result when using the Help/Report page for Chrome.

Anyone?
