Can't edit Google calendar events in Emclient but can do it natively in Google Calendar

I can’t edit Google calendar events in Emclient but I can do it natively if I’m in Google Calendar.
It seems like it’s some kind of permissions issue, I can open the events but I can’t edit them and they all show as italics in the Emclient calendar view.
I have full ownership of the Calendar to “Make changes and Manage Sharing” under the Google permissions but it seems that isn’t being picked up by Emclient. I was previously using the calendar with Emclient with no problems but I mistakenly deleted the calendar from Google and had to recover it from an Emlient backup and it seems now the ownership/permissions are not being sync’d correctly between Emclint and Google. I have tried deleting the calendar from Emclient and re-adding it multiple times to no effect.

Is there any method to bulk reset or strip the ownership permissions from events, I was thinking that may solve it?

Does anyone have any ideas on what I can try to resolve this?

I finally worked out what to do, you need to replace the “ORGANIZER” field in each event with one from your existing events that work fine. Right click on an event that works and select show as iCalendar and in the text view that you will be shown you will see a line that starts with “ORGANIZER”, copy that and save for later. Then export the whole calendar that has issues via File>Export and save as an .ICS file. Then open that file, which is just a text file, with a free code text editor like VS Code and use the search and replace function to replace the faulty “ORGANIZER” field(which will look something like ORGANIZER;CN=Family:mailto:***********@group.calendar.google or ORGANIZER;CN=:mailto:*********@gmail.com) with the good one you saved earlier, I did that on 2500 events and it just took a few minutes of fiddling. Once you have done that then save the now corrected *.ICS file and then reimport that back into Emclient into your Google calendar folder, all sorted!
