I'm not sure if I did something wrong or if this mod is interacting in a strange way with another mod.  I installed this mod at the beginning of the month.  It worked perfectly, and the image of the backpack was the correct yellow backpack.  A couple of days ago, I was using one of my other mods (Skinshop) and I noticed that the yellow backpack icon had changed to a picture of a garage door.  I thought it was a temporary glitch and would clear up after I disconnected and came back.  Two days later, and it still has not reverted back to the yellow backpack.  Here is the current look.

Backpack Icon??

Unless a garage door skin somehow got into your config, which I guess is technically possible (though not the fault of the plugin), this is probably a client side issue which you can resolve by clearing out some steam workshop files.

You can check your config for the skin ids and browse to them on the steam workshop to see if they are garage door skins. If they are, then you can replace them with the skins from the default config in the docs.

I appreciate the quick reply.  I apologize for being such a pest, but I'm new to running a server with config files.  Where you say "check your config for the skin ids", I assumed that it would be the config for the backpacks.cs file.  When I originally looked in that file the Skin Id showed 0 (zero).  I removed and reinstalled Backpack and Backpack Button.  After restarting the server to confirm changes, backpack.cs now had a Skin ID of 3050418770.  This corresponds to the original white backpack icon on Steam Workshop.  I changed this Skin ID to 3050420772 which corresponds to the right facing yellow backpack on Steam Workshop.  Despite this change after restarting the server, the garage icon still remains. 

I don't know if it makes any difference, but when the original icon disappeared, it was while I was in game.  I had just browsed the Skin Shop and picked a new skin for a garage door (not the one that appears, but a different one), and when I exited Skin Shop, the icon for backpack changed right before my eyes to the current garage door...It's not terrible, I could have picked a weapon.  At least a garage door is "kinda" a place to store stuff...but I prefer the yellow icon.

Btw...the SkinShop I use is the one here on Umod by Rustoholics.

That's a strange story. I've never before heard of a plugin altering the skins that another plugin displays. I'm not sure how that would even be possible. There is likely some other explanation. If modifying the skin ID in the config (oxide/config/BackpackButton.json) has no effect on what is displayed, then perhaps the backpack button isn't being displayed at all, or perhaps another plugin (maybe Skin Shop) is displaying something on top of it.
