When running a face panel test on my Element 2, the [Tab][Flexi][Format][Expand] half-moon keys will not light up while [Time] and [Data] do.
Description/Explanation of Issue
This is expected behavior. There are not LED indicators for those 4 keys. If you are ever curious which keys will light up vs those that will not, take a look at the virtual keys in face panel test. Any keys that have an indicator will have a little circle on them.
