I came across a couple of issues in version 2016.9.
First, in the Color Panel, the Sparkles/Brightness/Contrast values are not updating correctly when selecting between different effects. This seems to only happen when the second effect clicked has the default values for Sparkles/Brightness/Contrast. If the second effect has values other than the default then it updates as expected.
Second, in the Layer Blending Panel, the Blur value is not correctly updating its value. This seems to only happen when the second effect clicked has the default value for Blur. If the second effect has a value other than the default then it updates as expected. The slider correctly gets updated but the text box retains the previous effects value. This is also happening for the top slider/text box that is next to the drop down for the layer style.
I have opened up two issues for these in GitHub.
Please see the attached video for a demonstration.
