Hello,
I have just come across a possible problem on External BOM - Drawing list. No matter what order you specify for group header nor the token you use there is no way how to change the actual order of the groups (namely GA and Assembly, where Assembly is always listed first and GA second).
Please see attached url from Forum, where this was questioned the occurrence of possible bug has been suggested:

Thank you,
