Armor Protection and Parents Control

I've had this router now for almost a year, not too bad for the most part. What bothers me is that the router itself as gone in and randomly named devices like "Amazon Echo" thats not even close to being apart of Amazon. Also, I had the Armor protection enabled and I recently just disabled it. It too was giving false vulnerability reports and saying devices are connected that are not. The Parental Controls (like the Armor) is an absolute joke within itself. Selected device that I would use for my daughter and created a profile. Its ridiculous that I can't choose word phrases as apart of blocking sites. I basically have to go through the entire internet and block every address. I will not pay money for either one when they dont even do the job they were created for
