some items can't be grouped

[mateus3c]

Describe the Bug

I'm using KubeJS to group stuff and I noticed two issues:

1. some specific items seem to not group, for example, I tried to group the following but it doesn't work in game:

EmiPlusPlusEvents.registerGroups(event => {
    event.register("kubejs:spike", [
        "supplementaries:bamboo_spikes",
        "supplementaries:bamboo_spikes_tipped"
    ])
})

2. I also notice that we can't group items that have the same ID (items that are different throught NBT), for example: "caverns_and_chasms:tether_potion" and "quark:ancient_tome",

EmiPlusPlusEvents.registerGroups(event => {
    event.register("kubejs:tether_potion", [
        "caverns_and_chasms:tether_potion"
    ])
})

EmiPlusPlusEvents.registerGroups(event => {
    event.register("kubejs:tome", [
        "quark:ancient_tome"
    ])
})

I would also like to know how I could add specific items to existing groups, for example, by default EMI++ groups potions but I noticed a few modded potions don't get added to said group such as "unusualend:warped_potion" and "species:youth_potion"

Reproduction Steps

1. try to create group with NBT items or with "supplementaries:bamboo_spikes" and "supplementaries:bamboo_spikes_tipped"
2. launch game and noticed items are not grouped
3. close and game with sad eyes because it didnt work

Expected Result

items get groupped

2. We can group the same IDs but it's not consistent. Alex's Caves jellybeans can be grouped

yeah I just noticed that, I can group goat horns... what's the reason for this inconsistency?
