Power BI Desktop Data Load Error

I am using Power BI Desktop and have several different active and stagnant Excel docs feeding into the report. "Active" meaning that there are data connections behind these reports (feeding from an SQL database) and "stagnant" meaning that there is no data connection attached; they are just simple Excel docs with data that I keep updated manually. When I hit the "Refresh" button at the top, the active connections load just fine. But I experience errors with three of the stagnant reports:

I then click "View Errors" and it takes me to the Edit Queries page. From there, I am not sure how to identify the errors, what is causign them, or how to rectify them. (See photos below.) Has anyone else faced this issue, and if so, what did you do to correct the errors?
