Bug: Android mail app - Preview/opening do not correspond

I have the Zoho mail app on my SGS4, and notice that when two emails are received simultaneously, tapping one of them in the folder view will open the other, and vice versa.

The one-line preview does not correspond to the email that opens in the mail view.

This is consistent and reproducible for me. (I'm operating an e-commerce site, so automated email sending)
