Blue Iris IOS app is not updating the recording timestamp

Hello Vera friends. I have an unusual issue hoping you can help:

I have several IP cameras and Blue Iris on my iPhone. One of the cameras is triggered by my Vera controller via a scene and LUUP code. When I manually “run” the scene (via web interface into the Vera controller), the recording works, but for some reason, Blue Iris is not updating the “timestamp” of the latest recording. (Timestamp meaning the text under the video image which indicates how long ago that last recording was taken).

I have several other cameras which are all motion triggered, and for them the recording and timestamp work fine. I checked all the parameters… the only thing different in the camera in question is the option “Global DIO input bits” which I enabled.

Any ideas?

thanks so much in advance,
