General Question BurnTimeMFD not burning

[GodAtum]

As you can see here, BurnTimeMFD is saying it's burning the main, but it is actually not. Or maybe I'm doing it wrong? I enter the DV amount of 54.74 and click BRN. It burns for a second then stops, but BurnTimeMFD thinks it's still going.

Maybe the BurnTime is too long (1.3 hours)...?

I wonder why its so long. The Arrow is positioned in exactly the same place as the ISS would be.
