Armed Away by UserDeleted with Touchscreen

I am watching my mom's place while she has her account on vacation with Xfinity. I was out at her place last Thursday (4/16) and everything was fine, I set her alarm before leaving with no problems.  Today, my mom called ne and told me said she got a message that her batteries were low, she thinks it's for the keypad.  So this evening I go into her account to check on her home securtiy and I see that on today's date (04/20) her activity shows" Armed Away by UserDeleted with Touchscreen". I have not been out at her place since last Thursday, I'm the only person who has the passcode for her security.  Also, some of her rooms are showing "Unknown Error" and I'm not sure what that means.  I will be going out to her place tomorrow to check on things.  Any help understanding what is going on with her security would be greatly appreciated.  My name is on my mom's account, if I'm contacted, I can verify whatever is needed. Thank you
