Ender 3 V2 - Melted areas on the top of the first mm of layers - extreme jagged edges

Dear community. Can please somebody give me a tip what to try to remediate melting on top of the bottom layers of my PLA prints - screenshots attached. It is especially visible on the bigger flat surfaces. I managed to significantly reduce jaggedness by online tips, but this melting is driving me crazy. I tried levelling the bed with regular A4 sheet of paper several times (I know it is probably not ideal) - the screenshot of the Cura test is attached (not ideal as well). The temperature of the bed is 55, hotend 205. Thanks in advance.

Hello
It looks like wet pla you can tell if you extrude some and you hear a crackling noise or see steam coming off. This can be fixed by drying it out there are plenty of good videos using a oven or a dehydrator like this one https://www.youtube.com/watch?v=CTrG7OAlsEA
PlA should be kept dry to keep it good
Hope this helps have a great day :)
