Updates to slide master not reflected in subsequent slides

Since updating to the latest version of Storyline, we're experiencing a lot of issues related to themes and Slide Masters. I wonder if our issues are related to yours. 

Storyline keeps doing unexpected things, like replacing colors in the palette with shades of grey when I try to apply them to objects, doubling up animations on object groups, drastically changing the settings and position of objects that I copy/paste, and not responding to normal options in the theme (like background color). It also won't allow us to import themes that were made with older versions of Storyline. 

It's all very strange and time consuming to deal with. We really rely on themes and Slide Masters to keep things consistent and maintain an efficient workflow. Hopefully Support can help us get a fix!
