[17:29:11] <FoxT>	 fraxinas: These are artifacts from the parsing process. Basically the parser puts these UNIQ markers into the half-parsed text to ensure that wikitext is not parsed twice. Wild speculation here, but what may happen is that your Anträge get parsed when they are used in #set and are therefore added to the TOC again.
[17:47:59] <fraxinas>	 hmmmm okay, wild...
[17:48:11] <fraxinas>	 any idea how i could fix this?
[18:02:14] <FoxT>	 fraxinas: Not really. Building the page from scratch step by step and try to isolate and then solve the exact problem.
[18:02:34] <fraxinas>	 meeeeek.
[18:03:16] <FoxT>	 Not the whole wiki, just that one article + templates.
[18:04:00] <FoxT>	 But yeah, I think there is a good chance that you have to rethink your setup.
[18:04:19] <FoxT>	 E.g. avoid passing headlines to #set somehow
[18:36:47] <fraxinas>	 aww that's sad :/
[18:36:55] <fraxinas>	 would have been great
