@0709: thanks for screenshots. On first screenshot of your device Tab4 7" - it has to be an issue in Android. There are completely missing big black/blue dots on end of switcheds. Also second screen is little bit weird. Old Locus version on Ace2? Because on all devices it should look really same as on screen 3 - TabPro 10". Hmm ... hard to say what to do with first device. Is it same on all screens? Also directly in Android settings, are there used same switches?
@Michal, @JoxM, @balloni: I have to say, that in this case, I'm still not sure, which solution is best, so I'll try to give chance to simple rename of "Popup label" and we will see. Thanks for your opinions!
