I had this issue on a 8.6.1 with CKE (8.6.0).
after i removed an old rte-configuration from my RTE typoscript file, all three presets and the formatting worked fine. So maybe its not a bug in the CKEditor itself, rather your local configuration.

Hi Dirk,

you are right!

I checked my configuration bei the Web -> Info Modul and saw some old stuff for the RTE.
After removing the old configuration, the CKeditor loses no formating anymore

Thanks for the hint.

This issue is resolved
(please change the status, cant set this status by my self)

best regards and happy easter
