Unwanted page numbers showing on Google search

[ktnsmtn]

When my site shows on Google search, it shows page1, page2, etc., after the Website title. On the web properties, I have the title, not the page number. Is the page number a default, and if so, how can I remove it from showing on the search.

The first link on Google search is mine - Kitten Smitten

Thanks for your help.
