Readings wrong from third reading. And _always_ from third one.

I'm having massive trouble with my OpenScale. I've tarred it to zero and calibrated it with a one kilogram weight. After that I exit the calibration program and exit the menu to get the readings. In the meantime I do not remove the one kilogram weight. After exiting the menu, the first two readings are correct, but the third one is wrong (see the readings below this message). The weird thing is that it's always the third reading. I've repeated it about 20 times, and it's without exception, always the third one.

When I go back into calibration after this (and I don't touch the weight), it again reports 1 kg in the calibration again. In summary, it always works well in the calibration program, but after exiting, the values are wrong starting from the third value.

Does anybody know what could be wrong here?

Ok, after messing with the settings I now have it working. No idea why though, since I set everything back to how it was in in the settings I posted above.

So my only advice to anyone reading this: mess with the settings.. :S
