Hi, i am using JabRef (JabRef 5.2--2020-12-14--e9be339 Linux 5.9.0-4-amd64 amd64 Java 15.0.1) on Debian sid.

JabRef version on

• Mandatory: I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

After importing the Chinese essay, manually insert a space or comma, such as 杨 秀群, the citationkey will generate successfully, but the Reference section of essay will display "杨 秀群 "(there is a space between杨 and 秀群) , not "杨秀群".
How could you resolve this problem, thanks!
