Can confirm this is still the case in 2020. Finally got frustrated enough to seek the internet for help. Apparently this old issue isn’t getting fixed. To fix it myself, I have to keep removing all the setting in the Object Styles, get out, apply the style, reopen the style, and reapply my effects. And that seems to only work sometimes. Real hassle and I think I’m just going to stop using the Object Style manager and do just item by item effects.
