Something weird with TAG ? When I switch to TAG I get a few kh/s, maybe if lucky half of my current rate that CGMiner shows.
CGMiner shows me a hash on my single card at ca 250-300 Kh/s, depending on Intensity setting.
DOGE on the other hand is ok, CGMiner shows 100, 200 or 300 Kh/s, then my statistics on the pool show 100, 200 or 300.
I have to add, that I first started with DOGE, then used the web-interface switch to TAG. Maybe something to do with that?
I'm not able to reproduce this, but I'll try few more things. Just to make sure this isn't something simple, when you switched over to TAG did you wait watch the dashboard at least 10 minutes? That's how long it takes for the statistics to get accurate.
