What you are seeing is what I suspected. Pegasus Mail uses internal IDs for tracking just about everything associated with the folder list so it is not surprising there is a conflict with "My mailbox". You have nothing to lose except time by trying manual edits to the HIERARCH file just be sure you have a backup of the mailbox directory that you can readily restore if needed.
This may be more information than you care for but it will give you some idea of what you are dealing with (credit to Bob Kellock for these details):

Note that when
Pmail is opened it reads HIERARCH into memory and operates on the memory
version of it. While running, it only updates the disc version if a significant
change is made such as adding or deleting a folder ; trivial changes such as
expanding or collapsing a tray do not cause the disc file to be updated but any
such changes that have been made appear in the disc file when it is updated due
to a significant change. HIERARCH is always updated on closing Pmail even if no
change has been made during the session.
When Pmail is
opened it reads the header of every PMM
to extract the folder’s UniqueID to see if there a folder entry in HIERARCH
that has the matching UniqueID in field 3. If
field 5 of that entry in HIERARCH is Name_Unavailable then it gets
replaced by the folder’s title from the header of the .PMM.
It also checks that,
for each folder entry in HIERARCH,
that there is a PMM (see Note 1) with the same UniqueID in its header that
matches the UniqueID, in field 3, of the folder entry. If no match is found
then the title, in field 5 of the HIERARCH entry is replaced by Name_Unavailable.
Thus folders
which previously had valid entries in HIERARCH but for which the PMM no longer
exists are invalidated by the insertion of Name_Unavailable. Conversely where
PMMs have “reappeared” they are made valid and they return to the same tray as
they were previously (or directly under the mailbox where they were not under a
tray).
Furthermore any
PMMs found that have a corresponding PMI and do not have any type of entry in
Hierarch are entered in HIERARCH as direct entries under the mail box (i.e. not
in a tray) provided that there isn’t already an entry in HIERARCH with a
matching UniqueID to that in the header of the PMM.
<p>What you are seeing is what I suspected.&nbsp; Pegasus Mail uses internal IDs for tracking just about everything associated with the folder list so it is not surprising there is a conflict with "My mailbox".&nbsp; You have nothing to lose except time by trying manual edits to the HIERARCH file just be sure you have a backup of the mailbox directory that you can readily restore if needed.&nbsp; </p><p>This may be more information than you care for but it will give you some idea of what you are dealing with (credit to Bob Kellock for these details):</p><p><!--[if gte mso 9]><xml>
