Download to Excel - "Refusing to run query with no limit that Looker cannot stream incrementally."

[CherAcadeum]

I regularly download data from a Look (Excel format, With visualization options applied, Formatted, All Results).

In the last few days, rather than the expected data, this message is provided in the spreadsheet:  Refusing to run query with no limit that Looker cannot stream incrementally. Please choose a smaller limit or remove table calculations.

I’ve decreased the Row Limit from 500 to 250 to 100 to 25 to 24 (the exact number of data rows for a particular download), and still receive this message.  Another data set had just one data row, and with a Row Limit of 1, still garnered this message.

Is anyone else having this issue?  What is occurring, and how do I fix it?

Thank you!
