0. ALWAYS PROVIDE INFORMATION ABOUT MODLOADER (Fabric / Forge) AND MOD VERSION (For Example 1.19.2-8.2.10)
   fabric
   1.21.1-10.1.15

1. Describe the bug
   Cant use pick up and Void at the same time, using void with pick up will always get rid of items,

2. Write steps to reproduce the bug
   use void and pickup, and let pickup on dissallow, while void is allowed, and place specifc items in void, and then drop any item thats diffrent from the one in the void in order to see if it deletes that too

3. What is expected behaviour
   for pick up to place the item in the backpack since it isnt in the void slot.

4. Screenshots (If applicable)

Unfortunately Im unable to see the message, make sure you also set 2nd option properly.
You can set it in second option to match the mod id, then any item from mc you put in void upgrade will allow voiding to all items from mc.
I cant see your filter settings but I suppose it might be the case, please check that or upload working photo of filter settings

Any info?

this pic is what i copied

I can't reproduce this issue, any other mods you use?
