File share?

This is for halo 5, So I was building stuff in forge then I go to save the map and it says “file share full, not enough space remaining in your file share. Please delete before saving again” but I haven’t even saved anything yet so what do I do

If you read the thread pinned, you will see that they have had issues for a while, and they are working on them. See here.
