Multiple emails and Zip problem

*products versions - {webMethods Integration 10.15}

Hello all, so i have a zip that contains 4 different files and in my virtual folder, and i have an email task that sends me an email after the zip is copied to a remote machine.

The problem is that it sends me the same number of emails as the number of files inside the zip instead of sending me only one email with the zip files inside.

I have this problem as well in the zip task, it zip one by one instead of all files together in one single zip

I know i need to be in a In single-thread, sequential processing, but i search everything and can´t find how to fix it, here it is a print of my monitor folder and email task configuration
