why is forge forgetting my environment variables?

Trying to deploy an l5 site to forge,

I start by going into the site and creating all the environment vars for the database as they appear in my .env file but using the values the forge emailed me for database , user and password. im selecting the laravel 5+ checkbox on all of them.

they are all listed down at the bottom and everything looks good,

I hop over to the deploy tab and put in my git info and tell it to run migrations and click deploy.

I get this error message:

• Installing classpreloader/classpreloader (1.2.0) Loading from cache

• Installing laravel/framework (v5.0.20) Loading from cache

Generating autoload files Generating optimized class loader Compiling common classes

[PDOException]
SQLSTATE[HY000] [1045] Access denied for user 'forge'@'localhost' (using password: NO)

I know I set the password so I go back to the environment variables page and all 8 env vars are gone.....

what am I doing wrong here?
