Hey zyzzza, I just updated the version from 1.18.0 to 1.18.1 (to have parity with the chrome version) there was a bug on 1.18.0 that caused some websites tables to not sort. I'm not sure if this was the issue you encountered, or not. Let me know if updating the extension works. If not send me the URL of the website you are trying to use the extension on and I can take a look at it. Cheers.
