Is it possible to suppress/hide a non-breaking pop up warning message?

Hi Eric,

I just migrated from the default bootstrap theme to shinymaterial theme. One feature of my Shiny app is allowing customized user input through an editable table through library(DT). I had to make a few systematic changes here and there so that the UI is shinymaterial compliant. After the UI migration, everything in my app seems to be working the same as before, except for that editable table, where this non-breaking error message shows up for every number the user tries to edit:

Since the app works perfectly fine and is not breaking anything to my knowledge, I am wondering is there any way I could just suppress/hide this pop up window & prevent it from appearing? Asking this since I am not familiar with JSON/html/web UI, and it would be the fastest way to make my app up and running again.

Much appreciation!

Regards.
