Describe the bug

Repo: https://github.com/EpicBanItemTeam/EpicBanItem/blob/feature/api-8/src/main/java/team/ebi/epicbanitem/EBICommands.java#L91-L163=
It's looks like all caused by flags. The flag completion isn't correct.

---

Merge sub commands complete

This command only have flags. The complete shows the others

// Current command
final var test =
    Command.builder()
        .shortDescription(Component.translatable("epicbanitem.command.test.description"))
        .extendedDescription(
            Component.translatable("epicbanitem.command.test.description.extended"))
        .permission(EpicBanItem.permission("command.test"))
        .addFlags(flags.block, flags.trigger, flags.world)
        .executor(this::test)
        .build();
// Merged command
final var create =
    Command.builder()
        .shortDescription(Component.translatable("epicbanitem.command.create.description"))
        .extendedDescription(
            Component.translatable("epicbanitem.command.create.description.extended"))
        .permission(EpicBanItem.permission("command.create"))
        .addFlags(flags.preset, flags.block)
        .addParameters(
            parameters.ruleName.key(keys.ruleName).build(),
            parameters.query.key(keys.query).optional().build())
        .executor(this::create)
        .build();

The flag without param can't as terminal.

---

Flag with a param is fine

But not without. It's merged with a command that have a SNBT arg https://github.com/EpicBanItemTeam/EpicBanItem/blob/feature/api-8/src/main/java/team/ebi/epicbanitem/EBICommands.java#L92-L101=
