Problem with attributes / values

Hello!
The plugin does not work with attributes. When adding / editing a variant product in a value line, they are not. Writes “No matches found”. In the “Attributes” section, where I created the values ??in advance, they are. But they do not show up until you organize them, for example, by name. Maybe this is the problem?
If you create values ??on the page of adding goods, they appear in the value line. I mark “Use for variations”, go to the “Variations” tab, select “Create variations from all attributes”, but nothing is found. Written “Added 0 variations”.
Therefore, I can not establish for the goods different sizes and different prices for them.
Tried to do it in different browsers, on the local host and on the site also experimented. I looked through a lot of instructions, I do everything right, but nothing happens.

Check, it’s probably in the plugin itself error, it can after the update.

P.S. Sorry, if something is not clear, I used Google translator.
