Media Player mixing up all my videos

I download Media Player thanks to advice here. As my videos stopped appearing in Films and Tv App which I loved.

I am gradually getting used to it
All my videos are in titled folders, which mainly show up in the list in Media Player

However some of the videos are appearing with the wrong folders names above them.
Can you help please?
They are all there but appear with the wrong folders names above them.
EG Family videos folder says Garden inthe list Driving me nuts lol
