My variable not visible during debug in (Local) ssis 2014

Hi All,

Recently i deployed my SSIS package from 2008 to 2014(Still in dev Env), all working fine, but during my debug mode , i couldn't able to find variable list in locals (to see values) as you can see in below image, i have around 50 variable but not even one is listed? is there a bug in Data tool?

and also i just created new package in 2014 and tested variable that are working fine during debug, but not on migrated package?

Image may be NSFW.
Clik here to view.

Thanks
