It’s likely that your theme’s custom function.php file is overriding it. I had the same problem and did a search for “password” in my theme’s function.php file and was able to just edit it there.
This is a plugin. Did you recently install the Custom Sidebars plugin? I did and I started getting this immediately. There’s a thread about it on the plugin’s support page and the developer is working on it.
In the meantime, I was able to get it to go away by disabling AdBlock on the domain I’m working on. Annoying for sure, hope this helps!

I think I figured it out… it seems to be pulling the text box length from the styles for the Contact page so editing that will change the text fields for the newsletter sign up too.
