I'm sure they were made with wick pins and wicked after they were taken out of the mold. Normally, the hole is small enough that the neck of the wick tabs "grabs" the wax and stay in. Or the warning label on the bottom is sticky enough to hold the wick in. It really isn't too big of an issue because once you burn it one time, that wick will be stuck. I, personally, wouldn't sell them if the wick fell out, but it wouldn't surprise me that a Walmart votive wick fell out.
