I am using WebApp Builder Dev Edition 2.12. I have a 3 maps I created using the launchpad theme.In all of them I have an issue with the attribute widgets table popping up. Everything is normal until I open up the attribute table. After that if the attribute table is closed and I turn on any layer, an empty white box exactly the same size and position as the attribute tables shows up. To fix I have to togle the attribute table on and back off. Next time I turn a layer on it repeats. Anyone else notice this? Possibly a bug in the attribute table widget or something in the theme?
