Simon Not exactly sure which styles are not being applied for you however one assumption I can make is that maybe you are referencing the background colors. We just identified that sections were being imported with non-variable color values. You'll have to alt + click on the blue labels to reset them for each section which is unfortunate. We're hoping to resolve this issue soon. Very sorry for the inconvenience here.
If this is not the issue, let me know with some screenshots of what you'd expect versus result.
