No content visible since update to Page Builder 2.13.4

Since the last update all articles built with Page Builder remain blank, although the content is there. After some investigation I found that all divs belonging to Page Builder have the size 0x0. (Joomla 3.10.6)
The site is in our intranet, so I can provide a picture only
Any ideas?
Thanks
