Glitches in Manual Order Entry Screen

Have any other system vendors run into glitches with the order entry screen? I subscribe to a system (Tantra Trader) that has had numerous cases of trades differing wildly from what was entered in the user interface. Today was the most obvious example that something has to be wrong. The trade was a simple STC trade for one contract of @SF5. Instead C2 spit out 5 separate buy orders for 1 contract, leaving the subscribers long 6 contracts instead of being flat. This could not have been a “user error” by the system vendor – he would have had to click the wrong market direction and he would have had to click the Place Order button 5 times within the span of about 4 seconds. Not possible.

Could someone at C2 please look into this issue?
