Duplicate value found in getPages() in pagination component

[JLongoriaII]

Hi, I'm working with the laravel vue pagination version 1.2.0 and I'm getting this issue.

Seems that everything is working well, but when I change the page after page 5, the component didn't show "..." twice, just once (you can see that after one needs to show "..." and the next one should be 4)

and throw an error...

could anyone help me?

A attached some evidence to be clear.
Thanks in advance!
