SSRS dataset filter fails when data contains a dash

I’ve added a sub report to the purchase order form that prints the default bin location for each part on the purchase order. It seems to work until it comes to a part that contains a dash. Anyone have any suggestions?

My first thought is: the dash ("-") have a space in it? Like “Main - Bin”?
I have seen spaces causing issues in SQL queries.

Looks like this 13-B-183, no spaces.
