Prevent Addition of Blog Name to Meta Title

I have inserted a custom Meta title for a blog post but I see that Squarespace adds the Blog Title to the end. Is there any way to prevent this?

Example for the post https://www.blog.baligram.me/blog/whens-the-best-time-to-visit-bali-get-the-answers-you-need

Meta Title: 

When Is The Best Time To Visit Bali? The Ultimate Guide — Baligram Magazine

But what I want is:

When Is The Best Time To Visit Bali? The Ultimate Guide

Because the tool i am using to assess SEO recommends the title be no longer than 75 characters but by adding the '— Baligram Magazine' it takes me over that....

@ChristineDarbyThank you so much!
