Having two wildcards after each other in a sentence doesn't work

[salleq]

I'm trying to translate timer commands to Finnish.

I have this sentence:
{timer_command:conversation_command} <timer_duration> [kuluttua|päästä|jälkeen]

This doesn't go through tests or python3 -m script.intentfest parse --language fi --sentence 'avaa autotallin toinen ovi 5 minuutin päästä'

In English it's done like this:
{timer_command:conversation_command} in <timer_duration>

Also the two "variables" the other way round seems to work at least in English:
in <timer_duration> {timer_command:conversation_command}

This also works in Finnish, but goes a bit "poetic" ...
"jälkeen <timer_duration>, {timer_command:conversation_command}"

However in Finnish I cannot put the word "jälkeen" ("after" in english) like this because it's not proper language:
{timer_command:conversation_command} [kuluttua|päästä|jälkeen] <timer_duration>

Do any other languages have the same issue and is there a way to fix it?
Right now the best I can do is make a workaround like (translated to English):
"command {timer_command:conversation_command} timer <timer_duration>" but that's not intuitive to use.
