Can't remove child price

[Parsimonious]

Using Joomla 2.5.4 and Virtuemart 2.0.6

I used the generic child variant to create child products.
I put in different prices for each child to test it out.
Now I can't remove the prices and just rely on the parent price. I can change the prices, just not remove them.
I've tried to do it from the parent in the product description tab where the children are listed and directly in the child. Neither way worked.

This still seems to be an issue in 2.0.7f
