Cache issues

Hello, i just enabled my server speed optimizations like is seen in this picture https://www.dropbox.com/scl/fi/17fj2ub68numjkdpgmyyq/Screeneeeeshot-2025-01-27-132330.png?rlkey=cepi43i0r3xvl0ip75yt5mfo9&st=3i6xe928&dl=0 and im facing some issues with translatepress.

If you go to the link [ redundant link deleted ] and then go down to the end and change the language to greek?https://www.dropbox.com/scl/fi/db9l4xv5ja8z2xo42fjzr/Screenshot-2025-sss01-27-131722.png?rlkey=zuqutv0lzbwl116gk7tpyt71d&st=dk1fnlzi&dl=0?it should show the site in greek at first with correct translation. But if you press then the logo on the left which points to the index page it reverts back to english and the translation is broken?https://www.dropbox.com/scl/fi/vrl6ueg287ud58aij3c0t/Screenshot-2025-01-27-131655.png?rlkey=axrjkl9uucu799ufhb0yhw38m&st=a4m25vh7&dl=0?and?https://www.dropbox.com/scl/fi/jqh2yuqjg0oevbwdy4j5x/Screenshot-2025-01-2aaa7-131746.png?rlkey=ijfewo9rmuy8xpwckbl5fbkht&st=70yhyhz1&dl=0.

This is have to do with the server side caching. For some reason it caches the original language but then it fails to revert it to the translated one.
