multiple google calendars and sync of modified items

[stls]

Hi,

I got a strange thing on sync on the Galaxy modified appointments in a second calendar back to google.
The same thing with my main calendar are without problems.
I can create and delete appointments in each calendar (on the phone) which I sync between the Tab and google but modified appointments synced back only it the items stay on the main calendar. Any modified appointment in another of my google calendars are not synced back to google. Then it happends that the phone and the web calendar have both different items (different times,subject and so on). If I the modified the problem item in the web calendar I got on next sync two calendar item in my Tabs calendar. strange.

In the web calendar created, edited ,deleted appointments are syncing like a charm with no problems for each of my three calendars. (One main calendar, on for work, one shared with my wife).

Anybody here who know something about that or has same problems?
Is that a configuration, Tab, a Android or a google problem?

I tested already resync, delete+recreate the google account on Tab, delete calendar data, create a new calendar in the google web front end.

Best regards from Berlin.

I'm sure. the problem is located by Samungs calendar app.

anyway...
I just change my calendar app to the last version of pocket informant. That solve the problem. Changing an appointment in main and some more calendars are synced back to google calendar without probs.
