What do your file lengths say like in the screen above? Files will mostly be the same length (stereo files will be double what mono files are)... If you do indeed have a bad copy of a wav, a longer length or a different "size" will be a sure giveaway...
In addition, try:
1) Unzipping the original trackout zip again
2) Re-importing the files
3) Making sure the zip you got is directly from our website https://sfrbeats.com/orders
You want the files to line up like the below pic!
