Savannah mine seeds not stacking

[fiery current]

The seeds you get from the giant watermelon and cotton plants in the Savannah mine don't stack with the same quality of seeds that you've purchased from Sam.

I had osmium quality seeds from Sam's store already in my chest, and received osmium quality seeds from the Savannah giant plants. When I went to combine the two when I got home, they just replaced each other in the spot instead of stacking.

Update - Red bell pepper and strawberry seeds gotten from giant crops in the savannah also are not stacking. At this point, I'm pretty sure it's any giant crop's seeds that drop from the savannah. Which is a bummer.
