> and < Symbol in Pivot Table

[Warpug]

Ive created a data set using Power Query. From that Data set I am creating a pivot. The pivot works fine except for one thing, the date field includes the greater than and less than symbols and I cant figure out how to get them to go away. Any suggestions? Something Ive noticed, is that the dates on which these symbols are connected are a year apart, essentially <8/13/2020 and >8/12/2021 the only significance of that date is that it seems to have been when I built the query.
