Mail: Mobile App: Pulling contacts from multiple accounts.

I have the Zoho Mail App on Android (v 2.4.14) and have 2 "user accounts" available in the app (I only use them one at a time, that is, I don't use "all inboxes" option.

When I enter an email address the app pulls addresses from both accounts' contact lists.  This is very confusing as these accounts have very different contacts.  I would assume and hope that it would only pull contacts from the active / selected account.

Is there a way to have it only pull contacts from the active/selected account?

Thanks,

Todd
