The steps I have done are the following:
Site created in Joomla 3, with SPPB 3.6, then updated in each version until Joomla 3.10.10 and SPPB 3.8.8, the site was migrated to Joomla 4, then updated to SPPB4, after updating in the front-end the site looks like a mess, especially the border paddings and other configurations of each section, which being from the core and no customizations are added, must recover the assigned configurations. Similar with feature box, slideshow, icon and other addons.
Note: when you enter the editor it looks fine, but for these to be seen in the public part it is necessary to re-edit each section and addon, although the changes are there it is necessary to re-edit each section and addon, and this is not the behavior that is expected.
I hope there is a solution to this problem soon.
