Edited descriptions of multiple events and now they are gone

Using a Samsung Galaxy A30s and the Google Calendar version 2022.48.2-494681027-release. I have a weekly recurring event until July 2023 with two more persons. In order to add more specifics, I edited the description of each (from now until the end), saving "This event" as the next image shows Initially, everything was showing up fine and they received emails with the updates. But now I don't see the text in the description. The same happens in the Calendar of the other two persons. How to proceed to get back the descriptions in the events? Ideally I wouldn't have to do it all over again...
