How can I remove (1) in title tag

[Entelech]

I don't know why (1) is shown in the title tag. I show all of pages

I try to check {{seo_title}} value in theme.liquid

<title>{{ seo_title | strip }}</title>
<title>{{ seo_title | strip }}</title>
<meta name="Hello" content="{{ seo_title | strip }}">

Result

{{seo_title}} is OK.

but (1) being injected

Does it still happen if you disable JS?

What's the store URL so we can take a look?

Hi again,

 I had a look into this,

The chat widget/app you are using causes this. It's modifying the title attribute to notify the user that they have (x) new messages in the chat.
