Why does my Samsung S6 lock screen disable on its own?

Samsung S6 Lock Screen disabled on its own

I have had the fingerprint lock in place since I got my phone.

Yesterday the screen lock disabled by itself and no password was needed to get on phone. In addition, the Unlock effect "Water droplet" turned on.

Has anyone else experienced this?

Did you recently receive an OTA Update?

Not sure what OTA Update is.

It happened again today. The settings under "Lock Screen and security" then "Screen lock type" changed from "Fingerprint" to "Swipe".
