Unable to create new application folder, folder name duplicate

ubuntu 18.04.2
gnome-software [3.28.1-0ubuntu4.18.04.10]

When I grouped programs into folders, I found a Bug that could not create a new folder. This Bug led to the creation of a folder name that was created last time!
Operation steps

1. Check the game that comes with the system.

2. Click "Add to Folder" and create "游戏"(Game) Folder

3. Click the Add button

4. Check out several programs without canceling the previously checked games.

5. Click "Add to Folder" and select "工具"(Tools) Folder

6. Click the Add button

7. Check the game and cancel other programs

8. Click "Move to Folder" and select "游戏"(Game) Folder

9. Cancel checking game and check several programs of "libreoffice"

10. Click "Add to Folder" and create "办公"(office) Folder

Bug appears!

The name of the newly created folder is game.

我在对程序进行文件夹分组时出现无法创建新文件夹的Bug,该Bug导致创建的文件夹名称为上一次创建的文件夹名称!
操作步骤
1.并勾选了系统自带的游戏
2.点击“添加到文件夹”并创建“游戏”文件夹
3.点击“添加”按钮
4.勾选了几个程序，没有取消之前勾选的游戏
5.点击“添加到文件夹”并选择“工具”文件夹
6.点击“添加”按钮
7.勾选游戏，并取消勾选其他程序
8.点击“移动到文件夹”并选择“游戏”文件夹
9.取消勾选游戏，勾选 "libreoffice" 的几个程序
10.点击“添加到文件夹”并创建“办公”文件夹

Bug出现！
新创建的文件夹名称是“游戏”
