Insert hyperlink automatically doesn't work

Hi all,

I am using LibreOffice version 5.1.6.2 in a 64-bit Ubuntu Xenial OS.
The automatically hyperlink insertion on pressing Enter it’s not working anymore.
I’ve checked the Tools > AutoCorrect > AutoCorrect Options and the URL Recognition are both cheched, but is not working.
The only way is to do an Insert > Hyperlink for each URL, which is really annoying as I need to write a lot of URL references.

Does anybody knows how to solve it?
Thanks in advance!

Did you already try a reset user profile (or running LibO in safe mode)?
