This only occurs for the first time when Minecraft has not been started before.

commented

I haven't managed to reproduce this with just Lithium, it may be being caused by another mod. Could you try testing the same mods but without Jumploader, for example in MultiMC?

commented

Yeah, I tried it and have the same issue. It still doesn't work.
