For background discussion to this issue see http://community.logos.com/forums/t/23935.aspx
1. Anything does not specify any number of elements between two constructs ie. between Word 1 and Modifier 1 below the results show Anything is only 0-1 word with the default setting Occurs at least once.
EDIT: after removing Anything and putting it back the problem went away! However, the other issues still remain (this may have happened in conjunction with #4 below).

2. If the setting for Anything is changed it is not reflected in the Syntax diagram ie. Repeats 0 to 3 times is not shown above.
3. In this instance the unit for Repeats is a number of words eg. Anything is 0 to 3 words. Is this true in every case and why?
4. If I change from Repeats to Occurs (or another) the new setting is not enabled!
