Column Built From Other Column Formula Adjustment

I have this formula that I use to put a collection into my eReader from a column, and it works just fine. I get an end result of "R - Tag" or "N - Tag", which is what I want. However, if none of the conditions are met, I just get an R or N (which is also technically correct, but I'd prefer if it just stayed blank if that's the case). Is there a way to make it so that the field remains blank if there are no matching tag criteria?

Code:
{#read_status:}{:'list_item(list_intersection(field("tag"),sublist("Tag  1,Tag 2,Tag 3,",0,0,","), ","),0,",")'| - |}
