Playbar does not show adustet color but light-blue only

Hello together

working with Captvate 8 my problem is:

A few days ago all uploaded Scorm-Packages are suddenly showing playbar and playbar-Icons NOT in the color, I adusted them in the Skin-Editor (set to "black").

When I try to readjust the color i. e. to be "red" this does not come up within the published Scorm-Version.

Everywhere the playpars are with background-Color lightblue and the Playbar-icons are backgroud white and not as otherwise adjusted (black or red).

What the hell did happen to my Playbars???

Thanks for any hint.
