Songs not ending or closing when finished

[Shadow the Hedgehog]

One of my songs I made has encountered problem..
When first I made it in challenge level. It goes well when played..
Then when i continued to make the standard level and played, it can't end when finished..
It just keep showing the bg like the song is still playing.. I must quit to end the songs..
How to solve this matter anyone?
Thank you..

It sounds like one difficulty is ending later than another difficulty is.

What SM version are you using?

[Shadow the Hedgehog]

SM 3.9b
and for that one, all difficulties became un-endable after I made another difficulty

SM 3.9b

Please stop using this version. Use 5 and see if this problem persists.
