Not all rows returned post refreshed Excel upload to Blob

Hi... I've setup some reports that pull data from a Excel sheet place in azure blob. The Sheet (Say Mergedall) is a merg of 3 sheets (Merge1,2,3) to one.

EG: TAB-A has 105 rows, today I uploaded a new version of sheet (Mergedall), so same sheet, just with updated data, and post upload, only 34 rows are returned. the 34 rows are info from the first of the unmerge sheet (Merg1), so info is missing from 2nd 3rd sheets (Merg2&3). if I open the sheet (Mergedall) in excel, all the info is there (Merge1,2,3).
This issue is present in both Blob version and if I open (Mergedall) from my desktop in Power BI.

If i switch back to original (Mergedall) from the day before, allrows are added
Any help be appreciated. TIA
