labels are not displayed in polararea chart

Please maybe someone knows how to overcome a problem:

Created a polar area chart for test result

https://talantoved.ru/test/fields/1gb9283a142bcdb0f298aa93bec4fd1cbea/

Doesn’t display any labels. At all. Tried everything – numbers, english titles, to play with the size width etc etc, no result.

This is my current shortcode. Thank you in advance guys.
