[Plugin: Page Link To] Won’t open in new window

SO, I am new to WP and I’ve encountered an issue with the
plugin: Page Links To

I installed, activated and attempted to use but when I encounter the above mentioned error.

I enter the URL that the link should point to.

I select the box, Open this link in new window.

But ALAS, when the link is clicked it opens in the parent window and not a new window.

Any help would be well received.

thank you
