Hello,
You're right, and this is already solved in my dev version (the next major 3.6.0 which i plan to release before end of year if test period go fast, with alpha1 available for Pro users by the end of November).
So yes, today, keep using one date per event if you want to prevent this issue.
The next 3.6.0, with its new refactoried frontend, will check the date clicked, and auto select by default this date.
Later, i will see to add more option, as to display only the selected date.
In fact, many improvements were done in the past, and much more will come in a near future and later!
Thank you for your patience!
Best Regards,
Cyril
