FLAC Tags don't show up

Hello there people, how are you?

I have this one problem, I open some FLAC files in my Mp3tag 2.50 and I edit them, when I'm done I save them but they aren't opened by any player. I uploaded the songs to my MP4 player, which reads FLAC, but it doesn't read the tags neither my players on my computer. When I open them again in Mp3tag they have the tags, so I don't understand what's happening

If anyone have an answer to this thing i would aprecciate that.

you problem looks just like this one:
