Hilti Webinar Issue

Hello, I took the Hilti ACI 318 Shear Concrete Breakout Calculations (ANC210) webinar yesterday. One problem was that the original invitation did not note the length. Previous seminars have been 1 hour. It was mentioned at the beginning of the meeting that this was 1.5 credits. It went about 1.75 hrs long.
Yet the invite from Hilti sent to my email was for 1 hours.
There was no way to know the length of this ahead of time. Can you please convey to the relevant personnel?
