Dates don't work in cloud

Hi everyone,
I worked in Spreadsheets on the desktop version, which worked completely fine. Then I went on cloud and uploaded my files. In the cloud version dates simply don’t work as if they are not dates but texts. If I change them to Dates on the top where you can select the format, nothing happens. My formulas don’t work with dates but only with the ones I newly add. They show #VALUE!. The original ones work until I touch them.
Can you help me please?
Thank you!
