There appears to be no blendshape for ‘え’.
Also, facial expressions did not move in the MMD world.
I got good news, so as far as the E viseme not being there I added that , and now to get it working in MMD I had to use VRCfury's mmd compatibility component apparently something got a little too complex in the back end and it was interfering with mmd's usual operation, expect a hotfix patch soon ( I do not want to spam them too much but gunna tweak a few other thing so its worth while.)
