Mix & Render changes made with envelope tool

I have a song playing under myself talking and then use the envelope tool to increase the volume of the song after my vocals are over. When I go to mix and render the vocal track with the song track, it takes away the changes I made with the envelope tool. Any help? I’m using Audacity 2.0.5 on a mac using version 10.9.4

I included a screen shot of before and after mix & rendering.

Did you adjust the gain slider in the Track Control Panel?

No, should I?

It looks from your screen shots that the lower track is being mixed at a lower volume than the upper track. You can see in the mixed track that the envelope changes are still there - notice the increase in volume just after the upper track ends. This suggests that the Gain slider on the lower track may have been accidentally set quite low before the mix was made.
