Google Event (in Google Plus) is by default set only with date and starting time. Such event is then correctly displayed in the Google Calendar oly in that day (I guess with some default duration of two hours).
When such event is then synchronized to eM Client Calendar it will appear as an event with the correct starting date and time and with the wrong end date and time, it is set to 31.12.9999 23:59.
As a workaround you can set the end time to all your events.
However this is not an option with events organized by someone else and where you only participate - these events will be present for every day in your eM Calendar forever (or until the developers find some better solution). 
Hi,
Have you set those events set as recurring in Gmail’s web interface? Recurring events without end time will never end by design.

No, i haven’t.
Now when I double-checked: it is actually even not possible. Clicking the event in Google Calendar automatically opens the Google+ Event.

Hi,
i am not able to reply this issue at all, could you send me some of these event exported into .ics ( you can move them to other folder (desktop for example) or right click on it and select save as).
then also create GData logs - tools - settings - advanced, check GData under your account, apply and restart eM Client.
then create your events and synchronize them and if there will be another issue, send me those logs to [email protected]
please put link to this topic into email subject.
