Advanced AntiVirus settings reverting for no reason?

Hello! In the advanced settings of the antivirus there is an option to select what happens to suspicious files. During setup, I chose to send such files to quarantine however I noticed that the antivirus reverted back to the default setting of "take proper action". Which resulted in several of my files being deleted. No problem I just changed the setting to "send to quarantine" again but today I noticed that the setting was reverted again! This is really annoying and I don't see the point in allowing us to select what happens to suspicious files if the antivirus will just delete them regardless!
