Marketpress is removing product variations from product with no mechanism to upd

I am running WordPress 4.9.4 running Weaver Xtreme theme. We are using Marketpress plugin 3.2.7. I would classify myself as a WordPress novice.

I have set the Marketpress option to automatically hide (mark draft) any product whose inventory goes to zero. I also ticked the option to track inventory.

I am setting up reserved parking as a product where customers can view a parking map and then select a parking spot from the drop down. For this parking, I have created a parking product in the Marketpress store with variations of “Parking Spot #1” through “Parking Spot #5”. I set inventory to 1 for each and ticked the option to track inventory.

If I go and purchase “Parking Space #3” and complete the process, everything works as expected. When I go back and try to purchase another Parking Space, “Parking Space #3” no longer shows up in the drop down. This is great, this is exactly what I want.

However, when I go back to the parking product under the Marketpress store, under products, I see my parking product with 5 variations. However, when I click to edit the product, the variation of “Parking Space #3” no longer appears under the variations. If this was a product with no variations, the product that is out of stock would be set to “Draft” mode. For products with variations, I am assuming something similar is happening with the variation that is no longer in stock. I cannot find the “Parking Space #3” variation anywhere in order to reset the inventory to 1. I can re-add the “Parking Space #3” variation
from scratch again. This seems to be a PIA since we will be dealing with 50 parking spaces and would have to re-add for each event. I am assuming I am missing something obvious.

For product with variations that go out of stock and removed, how can I access the variation to update the inventory?

Thanks for reading. Any assistance would be most appreciated.
