Project playback faster than the original

So i had a project in cubase 12pro and after installing cubase 13 i decided to open the projects files in cubase 13,everything was fine till i noticed the projects were playing slower than the original so i decided to speed it up a little using the tempo track
Now i tried exporting my projects and they are playing faster
So please any help in solving it at the initial stage ?

Hi and welcome to the forum,

Make sure, the Project’s Sample Rate matches the Audio Device’s Sample Rate, please.
