license key removes itself, please move the license field

Hi,

Everytime i update a plugin WP Job Manager removes the license key and email address i used to purchase the premium version.

Can you please for the love of god take it out of the plugins menu and put it in a different place like job manager settings?

Re-adding it every time there is an update is so annoying. My friend that uses wp job manager just emails me the updated files because this is too annoying.
