[Incredibles 2] How were they just finding out about Jack-Jack’s powers?

Did they not notice what happened when Syndrome was kidnapping him? Especially when he was on fire. Plus they had a mask on him when The Underminer showed up so they had to be aware of it.

They couldn’t see exactly what happened with Syndrome and Bob discovered Jack-Jack’s powers very soon after. The events of the second movie immediately follow the first.

Jack-Jack was with them so needed a disguise. Can’t have a recognisable baby blow their covers.
