I am working in perspective making flex containers in flex contrainers to make a page that looks like an excel page with color toggling

A bunch of the flex containers have this meta red triangle symbol saying

does not match the regex pattern followed by symbols numbers and letters  
name is broken or something?  
I don’t understand what is wrong

Component names are not supposed to _start_ with numbers, only letters (containing numbers in the rest of the name is fine). Among other things, it makes referencing them from scripting somewhat annoying.
