Midi export Failed Cubase 10

Hello guys,
Please help. I have Cubase 10 and yesterday I tried to export my midi piano file. I exported it as always and then I put it back in my project, but midi track was totally different. A lot of notes and out of time.
I dont know what I did bad.
I have only one midi track in project. See pics.

Thank in advance Martin

Does this midi file have many channels?

Chanel 1 only

Can you attach the midi file so i can import it and see the results?
