How do I fix date display issue with VMerge in the new Google sheets?

Hi! I am trying to merge three columns worth of data-- one of which contains date information formatted MM/DD/YYYY-- from several sheets into a master. After running a VMerge in the new Google Sheets, all of the cells with blank date information display as 12/30/1899 in the master sheet. Does anyone know how to correct this? I would like the blank cells to remain blank in the merge. 

The other merged columns (one of which contains percentages) appear to be functioning properly. Also, if I run the same VMerge in the old Google Sheets, I don't have this problem.

I'm not the savviest Google Sheets user, so any help would be appreciated!

Thanks.
