Maybe some other persistent options change the behaviour. Can you try
with a fresh ~/.isabelle/Isabelle2016-1 directory, e.g. by renaming the
current one temporarily?

The history file is saved by jEdit whenever the main properties have
changed and are saved, and especially on editor shutdown. You can also
invoke that operation manually in Console plugin / BeanShell:
This refers to all "history text fields" in jEdit terminology. The
Sledgehammer / Provers field is just one of them.

This is indeed very strange. You can check these Isabelle/jEdit options
in Console plugin / Scala like this:
The GUI wiring refers to the same option, see also
While we are looking at the GUI: Java/Swing look-and-feels can
occasionally play nasty tricks. How is the situation with plain-old Metal?
