Jeff the underscore is not such an issue, I could make some changes in the code,
but the problem is that for some reason some of your products have a name like this:
BR etc.
whereas other start with
CR1 etc.
And it has to be either or. Either there is always that 1 or it just starts like nothing, then 2 etc.
It has to be consistent.
Option 1:
BR, BR2, BR3, ...
or
BR1, BR2, BR3 etc.
But problem is what you have now:
BR, BR2, BR3
CR1, CR2
