Hi all,

I purchased my router 2 nights ago and the night of settign up I set 9x static IP4 address reservations for some of my internal systems.  The next day I tried and when I click on the '+ Add' the area comes up askign for the MAC and IP I want to use, but then within seconds a grey area appears over it all which stops me from clicking on anythign inside it like the text boxes and buttons.  Below is a screen shot of what it looks like.  I have tried using Google Chrome, Internet Exporer, Firefox and even Edge, but they all do the same thing.

Does anybody know what is causing this and how I can fix it?  I still need to add 10+ more reservations like printers desperatly!

Thank you so much to those who respond.
