The Schlage FE599 and Yale T1L/YRD-120 locks do not support secure encapsulation for the association command class as shown in the links below. This is what leads to the issue you are reporting.
The 0.30.x firmware does not have a “fix” for that. It does have a change which makes it easier for support to workaround the issue for individual devices. Users impacted by this should contact support for assistance.
