Changes in the Google calendar: when searching through all calendars, there is no more information about which calendar the term was created for (there is only a circle of the desired color)?

Question

Google

Somewhere since Friday 09/10/2021, Google has changed: when searching through all calendars, it no longer shows for whom the term was created - that is, the name of the calendar (there is only a circle of the desired color). You can only look individually for each term separately.
Than it can be caused?
And what about those who wrote down this information along with the term itself?
