Failed to save modifications to the server. Error returned: 'The base version must not be negative

I am having the same error message again from a few weeks ago.  Cleared up when I rebooted my computer ??? but now back again.  If I knew what message meant perhaps I could fix issue.

"Failed to save modifications to the server. Error returned: 'The base version must not be negative when impact is requested for a transaction."

I had completed a BI file and was working fine but wanted to start from scratch to clean it up.  My original (3 months old) excel file has several tabs which are imported into BI.  When creating a new BI file with current excel file, all the tabs import okay from current monthly sheet except for one which has changed the least over the last few months.

I compared the two tabs in the files current and original and both are the same except for two rows of data.

What is odd is this !!

The original BI file still updates okay with the original file EVEN AFTER adding the 2 extra lines to the original excel file.

HOWEVER, if I delete that query file (tab from excel) in BI and try to reload the tab into Query Editor and BI file again, (from the original file), it too gives me the same error.

Only the update or refresh works without an error.

I did notice that the Query Editor in BI did not automatically use the first row as headers when the error occurred.  It does it correctly with all the other tabs.  I then tell Query Editor to use first row as header.  Even if I let first row be data or use a table for the tab, the same results.

I tried putting the tab info in a separate file and still got the same error.

Thanks for any help you can provide to fix or at least what message means.
