*** [OMEMO] Unable to build any sessions, the message was not sent (Myself message does not work) | Identical chat tab

OMEMO Encrypted messages to myself do not work (same device/client: Psi or Psi+).

It must be true: "options.ui.contactlist.show.self-contact"

Screenshot: https://i.ibb.co/3yV0ZCy/psi-myself-test-messages-one-with-and-one-without-omemo.png

Myself Unencrypted message is showed correctly (double and XEP-0184 is perfect): look example "Without" in this screenshot.
Myself OMEMO message does not work correctly (only one, and no XEP-0184 validation): look example "With" in this screenshot.

EDIT: I add several examples:

1/ Only ONE DEVICE without the own key of current device in "Known Keys" (but it is detected by the client but not added, problem): "*** [OMEMO] Unable to build any sessions, the message was not sent"
2/ Only ONE DEVICE with own key of the current device in "Known Keys": "*** [OMEMO] Unable to build any sessions, the message was not sent"
3/ Several devices, only one connected (the current device) and the current sent device has not a decrypted OMEMO message in tab "*** OMEMO encryption is enabled"

EXAMPLE 1: This account has not this own key in "Known Keys" section:

We open the tab:

[XX:XX:21] *** Contact has been switched: testaccount@domain1.tld/Psi+
[XX:XX:21] *** User1 is now Online [1]
