Adobe Express " ! " mark in a blue triangle & a downloaded font that I cant use.

1. Another surprise with Adobe express -  an Exclamation mark in a purple-blue triangle. What does it mean  ? 

a simple, canvas on which I am starting out and I see a  exclamation mark in blue traiangle on the text box why ? It doesnt tell why it is there, i searched this forum too, people have had there issues with many layered projects that had "!" in red triangle. But mine is so simple just 3 layers, the page, and 2 text boxes, i dont see any other layer on the side. 

2. Also another issue with Adobe is that its so unpredicatble.

I downloaded this font- https://fonts.adobe.com/fonts/bisbee-variable and it is reflected in my creative cloud, but in any of the adobe apps like expess or premiere pro I am not able to use it why ? 

Here it is downloaded in Creative cloud, I added it my project library in express as well. 

This font is unavailble to me in any adobe app, if i try, i tried it it in express & premeire pro, it does not work. Why ? 

Why such simple things are so unpredicatble in Adobe ecosystem ?
