Order stuck at processing

Set order to Integumen and i see, that order says “processing”, price moved on, so would like to cancel limit order, but cant as says processing:/

Is that a bug or needs some time? As stuck at processing like 30min or more

@Tony.V can u look at it? As saw u helped others

Ok seems over went through, but still strange that i was stuck at processing and could not cancel, glad it went through

@David maybe you can explain what has happened here?
