An “item with the same key has already been added”
exeption is thrown on eds[sectionname].Add(key, value); (line 1061) if the "name" string of the object or the subindex contains the characters "[" and "]"
like in
"Filtering time t1 [s]"
where the "[s]" is the unit of the "filtering time" in seconds

The "s" is erroneously interpretded and added as a key and so the next string that contains "[s]" e.g.
"Filtering time t2 [s]" is interpreted as the second occurence of the key "s"

CANchkEDS has no problem with the "[" and "]" characters in EDS files and checks it as valid.

Might not be needed to change but should be described.
