Reorder Level 0 shows as low stock

Reorder Level 0 shows as low stock

I have discovered in Zoho Books and Zoho Inventory that if the reorder level is 0 the item still shows up in the low stock filter. This is a problem as we have items we stock and items we don't stock but customers can still order and we get them in to order. Therefore we want to track inventory on everything but only want notifications on items we stock. 

Right now everything with available stock below reorder level AND anything with reorder level 0 and available 0 shows up in the low stock view. Surely the low stock view should be only items where available is less than reorder. If reorder and available are 0 then it should not show up as 0 is not less than 0.

I have also discovered a work around where blanking the reorder so instead of saying 0, it is blank solves the problem. My issue now is how to blank about 10,000 products. If I export and blank the field in CSV and re import I still have a 0. If I set a number other than 0 it imports but I cannot figure out how to import it with a blank as a work around. I have tried a space int he excel cell but that does not work. 

Please advise if you can fix this reorder 0 issue and if you have any suggestions on how I can bulk blank the reorder field as a work around.
