Yep the issue is, why i couldn't see them on same wallet.dat that was older and synced, but could see them in later one which is basically same wallet. Remains mystery to me. Keys should be same, but this is not related to electrum.
No i don't use private node or local one. My wife is able to use sign and broadcast fuctions on Electrum, i cannot. Something was definitely screwed up in my electrum wallet. Probably it was bugged from long time ago when i created it. But in end of 2019 i think it was already 3.3.8 so shouldn't have happened. Well hope it's a single case like this. As i was not able to find anyone with same issue yet. However for now i will stick with Core. Better wait 2 hour to sync than lose everything because of bug.
