Foreign language unsupported issue

Hi there,
I produce content related to flyfishing etc and my original videos are in Icelandic, my native. I have started producing videos in English though but my adsense account is being rejected because of the older videos being in a language that Adsense doesnt support. Is it enough to subtitle the older videos or do I need to remove them?
If anybody knows, please share, I have no idea how to get answers from adsense, they do not really seem to like direct contact
Best, Gústaf.
