IB API: Submitted order magically reverted to PreSubmitted

Guys,

I have a situation here... I'm investigating a reason why my trading platform sometimes leaves order not transmitted even if I specify

order.m_transmit = true;

I recorded messages from orderStatus method and figured that those orders change their status from submitted to preSubmitted... which is weird?

I always thought that PreSubmitted "state" can not me trasitioned to after the order is in Submitted state.

This happens rarely, but when it happens, transition between submitted to preSubmitted takes about 1-2 seconds?

Any thoughts?

 

Any details on the route, order type, instrument traded, ...? This may help people to answer.
