Page Builder CK - Feedbacks and suggestions

It comes at frontend (I would not care about that if it comes at admin).
Page comes when you add any string at the end of the web address.
You can test it at one of my site test.hub4b.biz/diasona/fi/
just add any string at the end something like that test.hub4b.biz/diasona/fi/kjhk

Please check that you have the latest version 1.3.2 and tell me

I have updated to 1.3.3, please test this one

Tested 1.3.3, result the same, instead of 404 page it gives same as on screenshot I showed yesterday((((. You can check same my url, now there is 1.3.3 installed.

is it an article with the pagebuilder editor, or directly a link to a pagebuilder page ?

When it's article with the pagebuilder editor, 404 works Ok, but page itself has encoding problem, see screenshot attached and as result, I can't use PB in articles. You can can also check it at test.hub4b.biz/diasona/fi/ajankohtaiset there are two same articles there, first original Joomla article shows everything fine, second the same article made via PB and characters like ä ö etc. are broken there. I already found that this problem pops up when content plugin is active.

When link comes to PB page than 404 gives wrong page (as I explain above, I can't make articles with PB).

Would be good to fix both problems.
