Sugar_cane problem

Hello. This is my first time asking a question on the forum, so please do not judge strictly. The problem is, sugar_cane can be put in water and nothing will happen to it. It seems that this should not be so and I would like to know how to fix it. I have the latest version of Paper at version 1.16.5

Do you have this problem on a fresh server with latest supported/recommended requirements, i.e Paper 1.16.5 latest build with Java 15.0.2, without modifying any config entries?

If you reproduce it on a fresh server with Java 11 and latest Paper, then you can perhaps create an issue on GitHub.

If you are not sure, ask on Discord.
