The signs were set on top of the barrels. you can add a note to them to what needs to drop into the barrel.
There is no item filter for the hoppers. I left it so any item can be dropped in.
If you like you can make a simple item filter to set any specific item you need to trigger the exit to open.
Here is a pic of a simple item filter you can add to the hopperhttps://ibb.co/tC0p1xP
Please make sure you add the Redstone torch under the hopper on the block in front of the repeater. This will lock the hipper filter.
also note there is a second comparator to stop bud powering of the piston.
In the hopper add the below
slot 1: 3 of the items you want to set as the key
slot 2: 1 filler item. (Best to rename an item)
slot 3: 6 filter items
slot 4: 6 filter items
slot 5: 6 filter items
Hope this helps. let me know if you have further issues.

Apologies i missed that. The skulk sensor is picking up the placement and causing the issue.
Simple fix is to place a repeater pointing into the other and add a level to turn it on when you want to replace the sand.
Once sand is replaced can turn the lever off again.
I have added a picture so you can check positions. If the image is not showing please use the link below.
