Issue with Define Expression List not displaying correctly

[simon4]

I have a repeating issue when editing rules that the define expression list does not update properly. Here is an example:

and here is what shows in the main rule screen:

Note that it is showing conservatory shade 5 when conservatory shade 5 is not in this rule. This is reproducible. I looked to see if anything like this had been reported but don't see anything. Am I missing something or is this a bug? Thanks.

Did you clone this rule? I reported seeing a similar thing here.

I likely did clone this as there is one rule for each shade. So that is probably the same issue.
