I'm not sure if it is the certain problem with the spiral coaster, anyway, I think its preset list works incorrectly if I have custom track which of its name contains non-english, such as korean.
Steps to reproduce:
테스트.TD6Screenshots / Video:

(Note that 원심분리기.TD6 is not a custom design of Spiral coaster, but it looks it is shown as an empty entry)
If I try to click the "" entry:

In English, if I try to click _Build custom design_ first without any clicking other entries, it works.
If I try to click the corrupted entry, it shows error message. Then if I click _Build custom design_ again, it shows the same error.
In Korean, whatever I try to click first, it shows the error.
Note that 원심분리기.TD6 is not a custom design of Spiral coaster, but it looks it is shown as an empty entry.
The reason it does this is because the Spiral Roller Coaster has ride type index 0.
This works for me on Linux, so it appears to be Windows-specific.
Is this also resolved by #10540?
@Gymnasiast Thanks for notice, unfortunately it doesn't solve this issue.
@Gymnasiast I've checked recent develop(2340206), and it seems that there is no problem anymore :)
