Django templates PyCharm

What steps will reproduce the problem?
1.Create django template in project and programm recognize it (It autocmplite and recognie django tags)
2.Reboot system
3. PyCharm doesn't recognize all HTML files as django templates.
I've already checked that Django sets as Python templates language and directory, where the file is located, mark as template directory

What is the expected result?
Possibility of using autocompliting and recognizing django tags in HTML

What happens instead?
This possibility suddenly isn't available.
