GMail delegated login sync problem

I have a GMail account that I use with eMClient, and that works perfectly.

Now, I wan to add a new account (which is a delegated account on GMail). When I set this up, I specify the delegated account as account name, but I will have to use my ordinary gmail account name for logging in.

When eMClient then syncs the new account, it syncs the contents of my ordinary gmail account instead of the delegated account.

Taken from log:

10:46:50 staffassociation.e-conomic@visma.com [IMAP]  Synchronizing subfolders: For folder staffassociation.e-conomic@visma.com/Vigtig information

The staffassociation.e-conomic@visma.com account does NOT have the “Vigtig information” folder. This one is taken from my ordinary account: benny.tordrup@visma.com
