ZWay suddenly detects Secure Command Class in existing device, reports incomplete interview

(Running ZWay on an Intel NUC with Z-Wave.Me USB stick)
It seems that every now and then, ZWay forgets the interviews for some devices and then requeries them. Sometimes it thinks that a device has the Secure Command Class, and reports an incomplete Security or SecurityS2 interview. This condition is easily cleared by hitting Call for NIF followed by Force Interview, after which the Security Interview line and the Secure Command classes disappear again. I'm not sure if this happens only with specific devices, so far it has occurred with:
- Fibaro Dual Binary Sensor
- Fibaro Wall Plug
- Danfoss Living Connect TRV
- Eversping Dimmers (these are ancient, over 10 years old, yet ZWay was insisting that it was missing an S2 Security interview)
The made-up security interviews are annoying but they don't seem to affect performance. Still, it would be nice to be able to lock the interview database against these changes (in general, or per device), so that once an interview is completed, it stays that way.
