How to remove the hash mark in Adobe Illustrator in text?

Question

Adobe Illustrator

Greetings
I opened a document once created in illustrator, I write the text and a lattice appears to the right of the text:

Where does it come from - HZ, but I can’t remove it. In the new document, this lattice does not appear in others either, but in the right one there is some kind of garbage :(
Tell me how to remove it, maybe someone came across this.
