Ksk metadata filter error

[shinji257]

LRR Version and OS
Docker - 0.9.1

Bug Details
When using the Koushoku.yaml metadata plugin I'm getting the following error.

Error while processing ID 43140aeebd8c237a47b7db6401e1eae74a4b652b (Can't use string ("T-Heaven") as an ARRAY ref while "strict refs" in use at /home/koyomi/lanraragi/script/../lib/LANraragi/Plugin/Metadata/Ksk.pm line 81.
)

Matching Logs
No external plugin logs appear. I get the above when trying to do a batch.

Screenshots
N/A as it would just be the above text.

Additional Info
I'll note that where I got my archives from the format that they used changed a little. Fields like Artist and Circle used be set as a yaml list where now they are just on the same line.

So instead of

Parody: 
  - Original Work

It's now

Parody: Original Work
