problem with text and html editor

hi,
i started a new site. totally frsh installation. nothing other installed then classic editor, pagbuilder and widgets bundle. as template i use vantage.
if i use the widgets html editor or siteorigin editor i have problems with displaying my entered text.

e.g. if i type the following:

I
typed
this!

the text output on the page looks like this:
Intypednthis!

If i use the normal texteditor to create a post, there is no problem with the textoutput. Only if i use pagebuilder row and siteorigin editor widget in the post. Then the same problem with the text output occurs, as mentioned above.

an old but updated wordpress installation with pagebuilder and widgetbundle is running on the same webspace under another url. no problems like this with that installation.

any suggestions how to solve this? maybe its just a small thing i did not see.
