It means that you'll have to use software to manually switch from normal charging/device mode and USB OTG mode (e.g. plugging a USB mouse into your phone).
The phone won't be able to detect whether it's plugged into a PC/charger or whether you have some USB device plugged into it that you expect to work.
The fix is to desolder a couple tiny switches that aren't particularly important. I've completed that on my phone, I can confirm it fixes the issue.
As to whether to cancel your order, I suppose that depends on how critical automatically-switching USB OTG support is, and/or your comfortability with desoldering a couple little specks from the motherboard.
