Noticing a bug with the Pagination. Here are the steps to duplicate the issue:

1) Visit this page: www.mfg-furniture.com/living-room/stationary-upholstery

2) Click on page 2 of pagination

3) Click to a different page, any other page in the menu is fine

4) Navigate back to the original page (->Living Room, then -> Stationary Upholstery) in the main menu

5) The pagination is still on page 2 and should reset back to page 1 but it doesn't.

Please advise, thank you,
