Just had this cabinet installed , it appears to be either missing the bottom shelf or lip, as it only measures 10” deep . Is the bottom lip an extra ?

Thank you for quickly shopping out a shelf , however I believe we received the wrong size shelf , it does not fit this cabinet at all .

This shelf should be about 17-3/4" deep. If you see something different or have additional questions, please connect with our Customer Care Team. We can be reached at 855-768-4292 to assist with your questions, and we hope to hear from you soon.
