Recolored Bears Turn Back to Original When Restocked

[geekily]

Hi there,
I spent a long time downloading all the teddy recolors I could find and stocking my shelves with them. However, I noticed that when a shelf is restocked, the bear recolor turns back to the normal bear color. Is there a way that this can be avoided, or do I just need to not place these items for sale? Thanks a million!
