Randomly outgoing encryption does not work

[johntiror]

Sometimes, but not always, the encryption of an outgoing message can't be decrypted. Here an example where I didn't change anything before encrypting again.

Here the content of 'a' variable ready to be decrypted:

Here I decrypted it:

Here I re-encrypted without changing anything: (notice that it's different from the original)

Here I try to decrypt again but it gives me error:

If you want I can give you privately all my keys so you can debug it. Thanks
