Mac App Store glitch? "Install" button disappears on rollover. (More inside)

Trying to download certain apps, when I rollover the "Install" pop up box (after clicking the "Get" and "Install" buttons beside the app name itself), the Install button disappears, then reappears when I take move the cursor off the box. Like it's playing hide-n-seek.

Things I've tried: Making sure the apps are compatible with my Mac; restarting, making sure all updates are current.

I'm on Mac Mic M4 with Sequoia 15.5
