Can't change variable name or delete variable

I have a struct xxx with a field struct yyy containing 2 fields aaa and bbb of simple values. - With the variable editor I can double click on xxx, then yyy to see the column of 18 <1x1 struct>s. - Double clicking on any of the latter opens the variable editor table showing fields aaa and bbb for editing. - I can then right click in empty space in table to create a new field ccc. - when I right click on ccc to delete or it, the editor acts as if OK but nothing is done. - when I right click on either aaa, bbb or ccc to try Rename I get the error message name not allowed despite it being a short and fully legal combination of letters only (have tried many without success).

CAN ANYONE PLEASE HELP ME UNDERSTAND WHAT IS WRONG?

Please post the code which you use to create the struct. Following the textual descritbtion is prone to errors.

Then post the name you are trying to use without success - there is no chance that we can guess this detail.

Every member of a structure array must have the same set of field names in the same order. Editing the field names for a single member of the array is probably not going to work.
