Thank you! That’s really the better way!

Hi,
to solve this issue, you have to deactivate the “Custom fields” synchronization under Language -> Settings -> Synchronization. In addition, do not translate the locations and organizers (just create an entry for each location/organizer in each language, but not translate them). Then you can edit the events and the other language version will not be “damaged”.
But remeber: All changes (not only location and organizer, but also time and date!) must be changed in every language – they will not be synchronized!

Unfortunately I have not yet found a solution to this problem, which I also have. However, you can deselect the custom fields under Languages – Settings – Synchronization. Then the venue and organizer will no longer be overwritten with the wrong language (but this also means that changes to the date, time, etc. are no longer synchronized). Maybe it’s because Custom Content Types and Taxonomies are disabled and cannot be enabled …
@chouby: When editing a translation, the events all receive the same ID for the taxonomy mec_location, although there are separate translations for the different venues. Is it a bug or how can it be changed?

Thank you for your answer. After installing the query monitor plugin I saw, that you’re right. The sync of the post-metas from Polylang is the reason for this bug…

Since I have the same problem as @annakelemen , I wanted to briefly ask about your solution. Second, I think Polylang is doing its job right here. I can understand @webnus that you say if the location changes it will be another event too. However, the task of Polylang is precisely that the location (e.g. Germany) is given the correct name with a different language setting (in this case Deutschland). Polylang knows exactly that Germany and Deutschland are the same place and also establishes the relationship between the two names.
While MEC not only deletes the location but also the organizer, the category remains interestingly. Perhaps based on this observation one could establish a joint use of MEC and Polylang. It would be really great!
