Updating excel files on box - keep getting error code

Good day!  I am wondering about a recurring problem that I am having when I try and update an excel file in Box.  There are times when I am trying to move/copy a spreadsheet into another excel file and I get the error “Excel cannot insert the sheets into the destination workbook, because it contains fewer rows and columns than the source workbook.  To move or copy the data to the destination workbook, you can select the data, and then use the Copy and Paste commands to insert it into the sheets of another workbook.”  And for the most part, I can do this.  However, I do have certain worksheets that I am trying to move into another workbook that have graphics where simply copying and pasting doesn’t work.  I am wondering if this is an issue because the workbook is in Box or if its an excel issue.  Has anyone else experienced this?  Any guidance is appreciated.  Thank you so much!
