How to stop Google from eating event texts

I am using Messages version 14.5.20.5. After the most recent automatic Android update (One UI 5.1), Google is eating texts that contain event links. An "add event" button briefly appears and then disappears. About 30% of the time, an event is added to my calendar but it doesn't contain any useful information (not even the link nor the name of the sender). So basically these texts are lost. Presumably, Google was trying to implement a feature that would generate a useful calendar event from texts. I don't need such a feature. How can I turn it off? (Also how did I give Google the indication that I wanted this feature turned on in the first place?)
