Joe, I think all the callsigns coming out of Guinea have had the 3XY prefix for
at least the past 6 years. I believe an exception is warranted.

The behavior you described is no surprise to anyone who has read the
definition of what's treated as a standard callsign in any of the slow
modes in WSJT-X.
See, for example, the original defining document for JT65:
J. Taylor, K1JT, "The JT65 Communications Protocol" (QEX,
September-October 2005, p 3):
http://physics.princeton.edu/pulsar/K1JT/JT65.pdf
... or the WSJT-X User Guide here:
http://www.physics.princeton.edu/pulsar/K1JT/wsjtx-doc/wsjtx-main-1.8.0.html#PROTOCOLS
Relevant text:
"A standard amateur callsign consists of a one- or two-character prefix,
at least one of which must be a letter, followed by a digit and a suffix
of one to three letters."
The callsign 3XY4D does not follow this worldwide standard convention.
For this reason, the messages you showed are all treated as free-text
messages.
I am sure it is very frustrating for 3XY4D, and also for those trying to
work him (as I did, yesterday, by using free text messages in FT8).
In principle, we could make a "3XY" an acceptable, three-character
prefix, as a special case. Not a very attractive possibility, but...
