Some themes don't work

Hello admins. Appreciate that you activated some choice of theming on this site. Wanted to try them but found out that only part of them seem to work. I have no desktop availble for now, so can't help any more with debugging, sorry. Here is what desn't work:

darkly-red (seems to be the same as darkly, no red buttons as in litely-red)
darkspace (no CSS)
lora-compact (no CSS, but something "compact" might become my favourite!)
lora-distractionless, lora, mintybubble, winternord (no CSS)
