The cut-off amount for showing the first 15 values for a concept info page should be more than 16

[joelit]

At which URL did you encounter the problem?

https://finto.fi/yso-paikat/en/page/p94081

What steps will reproduce the problem?

1. See the "show all 16 values" button
2. Press it
3. The button is replaced with the 16th property

What is the expected output? What do you see instead?

Maybe the same amount of UI real estate could be just used to show all 16 values to begin with. This also brings up a question: What is a reasonable amount of X values for Skosmos to cut it off to first 15 and the "show all X values" - button. 16 seems a bit silly. Would 20 be better?
