Sample type field doesn't show all data in the setup

Hello guys,

I have a bug on sample type field when I want to create an analysis request. On my setup there is 461 data but when I click on the sample type field only 30 appears. How can I fix this please?

If you start typing a name, does it filter down to 30 more relevant items, or does it ONLY give you the option of the first 30?
