MPro Mesh App Parental Controls Bug

I have a MPro Mesh App to control my Trooli FTTP EX5601/EX5600-T Router. Which is all running well on 26 devices but as soon as I try and link my Sons Meta Quest 3 to lock down the hours it selects another device on my list. This can be at random but it just doesn’t seem to want to add the Meta Quest 3 to the group. As below.. select Meta 3 and then further up the list Wilbur’s Echo is selected. If I unselect it then it unselects the Meta.. any Ideas??
