How can I delete a filter from a DataSource?

Hello! I added a filter to my data source which combines multiple databases, how can I delete this filter. I cannot delete the filter, I can change the filter by scrolling through the fields, but I do not see a way to remove the filter. I am using Windsor.ai as my data connector. I tried deleting the data source and re-adding it to no avail. Please help.

Thank you,

Lynne
