Hi @Lydell28045759qr6z, Which platform are you using, Adobe Express, & what format are you downloading the project in? Is it a mobile app (Android/iOS), or is it on a browser on a desktop?
If you're working on a desktop device, you can try working in incognito or private browser mode to see if it makes a difference. Also, if you can, share a screenshot, or a screen recording of the workflow you're using that causes the wrong exports of those files; it would help us better understand and investigate the issue.
Best,
