Music info update

Some time after closing music player and KLWP app, music wiget (made in klwp) stops responding to music switching. When i switch the music cover and info still same. It fixes with opening klwp again, but i don't want do it every time. I'm already tried all teoubleshot tips. What's wrong?

Now i am using standart MIUI player in Redmi Note 4

And one more thing. Only music player controls does not affect music widget. When i am trying to switch music with widget controls all is working, but song info on widget and current song is different
