e-visa valid dates

Hi there,

I've have received approval for my e-visa with entry date of 29/09/18. In my application I had the exit date as 01/10/18, however, the approved e-visa has 14/10/18 as the exit by date.
I will be exiting Vietnam on the 30/09/18 and will be returning on the 14/10/18 and plan to apply for a second e-visa for this, once I've exited Vietnam. Will the exit date of the first e-visa affect my application for the second e-visa as it's the same date - 14/10/18?

Thanks
