Why does my business hours keep changing to something other than I assigned?

We have a 24/7 schedule. Sometimes randomly, our Ring Central system will change ITSELF to a 9:00 am to 6:00 pm schedule. Why does this keep happening? After I immediately notice I have a voicemail when my phone doesnt ring, and I have to go back in and change this back to 24/7 schedule. This has happened 4-5 times since we got this system. What is happening? :/
