Live editor image: https://prnt.sc/sCFilXeJRdDp
In the image of the live editor it is seen that the configurations have been recovered, such as the class, the paddings, etc. even the configurations of the addons.
Public part Imge: https://prnt.sc/GQf_4DTNSuzg
But in the public part it does not retrieve these settings as you can see it has only retrieved the class of the background color of the section, and the class of the addon but not the size of the icon that is in the addon configuration.
In order for the section to be seen in the public part as in the editor, it is necessary to take the 3 steps described in the image of the live editor, just do that 3 clicks because the data is there and it is not understood because in the public part it is not is recovered as well. Many times the same thing happens with the addons, but in some it does not solve.
Note: if you see the image of the public part, the previous section does have the padding (bottom) recovered and I think this is because those sections that are recovered were edited with version 3.8.7, but the sections that were created with previous versions of SPPB 3.7, 3.6 3.5 (I don't know from which version exactly) are the ones that don't recover in the public part, only in the live editor. I think that if they start to update their templates created with that version of SPPB they will realize what I'm talking about.
This was a bug report. Cheers
