Issue description: This appears to be a reaccurance of Issue #5729

Steps to reproduce:

1. create a digital miner with a power source
2. use tag filters "oreIron" or *ore
3. image does not appear after check, saving the filter is still possible
4. starting miner does not mine the ores.

Version (make sure you are on the latest version before reporting):

Forge:30.0.36
Mekanism:9.9.2

Another thing that I have noticed is that the miner loses its energy buffer similar to the energy cube issue in #5768. Strangely enough, standing on a charge pad with the empty buffer will actually recharge the miner.

Those are not even valid tags for 1.15 what you tried.

Im an idiot, I did not realize they were changed, I used to be able to use oreIron in an older version, thanks for the help.

You are correct that you used to do oreIron :)
OreDicts changed into Tags with 1.14 (or rather, Vanilla introduced Tags in 1.14)

How do you do to see the tag in your JEI ?

f3+h but i have kiwi installed

I believe you can use a dictionary on obsidian and it will show any tags it may have. I don't know offhand if obsidian has any tags by default in forge/vanilla.

Is there a way to see what commands work with the tag system? As I want to mine some obsidian that i know there is a large pool of it underneath my base but IDK the tag for it to mine it and I've tried "obsidian", "*obsidian", "*minecraft:obsidian", etc

You cant see tags via JEI atm its broken, wandering if anyone has an external lookup for this stuff.

How do you do to see the tag in your JEI ?

In terms of tag for a specific material, this seems to work.

Mekanism "Tag"
F3 tag info - I think
