Can't Save Product Metadata

Love your plugin so far, I’ve tried almost every other one, and none of them ever did all that I needed. Your’s is very close to that goal of letting me add all the metadata that I need. However, I can’t save the meta for products.

I have a review post that I am trying to fill out the metadata. The first time I tried to put Article, Product, and Review in and couldn’t save anything. Try again, this time put just article and save. then added product to it, saved, but when I went to add the review info, the product info was gone. Saved the review info, saved and then tried to enter the product info again. Still no luck.

I also can’t save the US as my country on the main settings page.

Also, the rating box only takes whole numbers? The same thing with the price field?

When I validate what I’ve already put in, Google throws a warning because there’s a empty “Customer Service” field. I don’t have a phone # to be reached at, so I haven’t filled that field out.
