The 3.1 version of the extension on TB 91.8 would repeatedly select an identity that was for archival purposes only and should never have been used for replies. Even after unchecking the affected email address and restarting Thunderbird, the problem persisted until I deactivated the extension completely. This issue occurs if one uses the REPLY TO or the REPLY TO ALL icons in the body of an email message.
Once the extension was disabled when I replied back to an email the From address used the correct identity.
