Pitch automatic changes!

I searched almost all forum and didn’t find the answer of my question. My problem is that few projects after opening are changing pitch (automaticaly). Is here salvation? Thank you!

Thank you for quick reply. I converted to 44 000 - 24bit. There was 48 000 and 16 bit. Solo wave, track converted good, but others spunds 2x slover. How to make all tracks the same rate?
Regards, Thank You!
