2000+ line pt2.

Sorry guys I sent the last post prematurely. So ill reitterate: Im grabbing descriptions for items on each line from the web & plugging them in column E. Then in column O im plugging in the website, followed by the price of the item in Column P. Utilizing the 'XLOOKUP' formula like this

=XLOOKUP(E2778, E$7:E2777, O$7:O2777, "") note i did not start the formula on line 2778. 

 Ive noticed in some instances when I grabbed a description & plugged it in column E, O & P would auto pop the web link & price! So how did that happen & how do i repleacate it lol?
