When navigating the Hierarchy menu, when you hover the title bar action, the option is nearly invisible. In addition, our previous version was 18.104.22.168 and did not have this issue. When searching the style sheet for the hex value, the value is not found. The new 22.214.171.124 style sheet was loaded.
The style sheet needed to be updated so the text is more readable. Moving forward, the links in windows that display hierarchies now have higher contrast when hovered, in order to increase readability.
