Many problems with Webstorm

I was very happy with Webstorm for developing.

New release provided very interested functionnalities.

Unfortunatly, that was 6 month ago.

At starting of Webstorm 2017.2 (or 2017.3), Webstorm :

- don't understand my code formating

- don't understand ES6 import except very basic import. That mean mouse navigation (ctrl + right click), and automatic import ( alt + enter) don't works and many errors on my editor bcause unresolved variable.

I would like to know if there is something to do to correct theses problems or you have the same problems than me?

I have Webstorm 2018.1.rc1

Best regards
