Using an existing Tasks folder in GMail

I recently had to reinstall emClient from scratch and I’ve discovered that the Tasks I had in my GMail account (created through emClient) aren’t coming up.

The Tasks folder is listed in the New Folder dialog for Tasks, and it now appears in the Email folder listing but I cannot assign it as tasks.

Is there any way around this so I can restore my Tasks?

eM Client never supported gmail tasks and it won’t be available even in the next major version due to problems on Gmail side (their API framework still doesn’t work). We will need to wait a little longer for them.
If you created gmail task folder using New Folder dialog, it is not really synchronizing with google and is locally only stored. Therefore tasks from this folder can be found in your disk database only.
