"Advanced Find" Settings not Persisting

When Loading a Session, and entering advanced Find (ctrl+shift+f), The Find options always revert to "Current File", no matter what state it was when Qt Creator was last exited.

The Find settings are successfully saved to `~/.config/QtProject/QtQtCreator.ini` on exit. The correct state is saved as:

[FIND]
...
CurrentFilter=All Projects
...

However, when next loading a session (any session). The settings file is reverted to:

[Find]
...
CurrentFilter=Current File

...

This same behavior is found in the session.qws files, where a XMl tag of

 <value type="QString" key="CurrentFilter">Current File</value>

is always added, even when deleted or overwritten with another value.
