Remove watermark made in media encoder from Premiere Pro 2020 export

Hi,

I made a watermark preset for my proxy files in media encoder as I shot my material in 4k. All my clips in the premiere pro timeline shows this watermark, but now that I'll export the film, I need to remove the watermark... How do I do this? Do I have to remove the watermark from the media encoder and make proxy files all over again?:/ Please advise, I'm lost.
