Can you help me find out how to use a specific pickaxe to mine beacons

I went to use #mine beacon it started mining the beacons but switched to the 1st hotbar slot. So the server wont let me mine it as it is using the wrong tool.

Final checklist

• I know how to properly use check boxes
• I have not used any OwO's or UwU's in this issue.
