Conditional Formatting not Working

I have a dashboard report I'm developing that will allow a user to select from a drop-down list (validation list) the type of report they would like to view. Based on the type of report they choose, I've used conditional formatting to format the cells. For instance, one cell, let's say cell A2, may need to be formatted as currency for the first report type and as a percentage for another.

I've used the following three formulas in separate conditional formatting rules in the same cell to change the format of the cell based on the value in the validation list.

=MATCH($B$2,Result_List,0)=1 - then the format would be currency
=MATCH($B$2,Result_List,0)=2 - then the format would be a percentage
=MATCH($B$2,Result_List,0)=3 - then the format would be currency

The issue is, when I change the drop down, sometimes the format in the cell changes and sometimes it does not. I think it has something to do with the order, but am unable to determine the cause...

I've gone thru a few different iterations with the formula and still can't determine the root. Please see the attached the file. The drop down validation list is in cell B2 with the conditional formatting issue in C8.

It's still not working. If I enter the cell (F2) and hit enter it changes, but when I use the drop down it does not.

It's in auto-calc mode. I wasn't going into cell F2, I was using Function F2 to enter the cell. If I change the drop down to Operating Efficiency (% format in C8) and then change the drop down back to Production or Accounts Receivable, the format stays in %. It does not change to currency.
