Known issue

Problem:
After update we found few problems:

1) Bottom footer is no longer translated (https://www.pcc-prodex.eu/en/ -> bottom part of the footer)

2) All words in headers and subheaders starts with big letters (?)
eg
https://www.pcc-prodex.eu/en/faq/how-do-you-prepare-a-room-before-spraying-foam/

3) Fields I have never wanted to translate (and its set in translations settings) appeared in translation editor and we got less than 20% completed (before update it was 100%)
It causes problem when we do changes on product and on translation it does not appear because translation seems to not be finished...

How can I fix this?
