Auto-complete deletes code right of the cursor when key is pressed fast

When I press enter or tab to apply the auto-completion it removes all the code from the right of the cursor. For example:
I have the code enemy.attack(enemy.getAttack());
If I want to auto-complete the enemy.getAttack() part it will detele the bracket and the semicolon after the method is inserted. I've tested on 3 different machines with different code and it still happens. But only when I press enter or tab fast after the auto-completion window pops up. If I wait a bit and then hit enter it inserts correctly.

Environment

• Operating System: Windows 10 20H2
• JDK version: 15.0.1
• Visual Studio Code version: 1.51.1
• Java extension version: 0.72.0

Steps To Reproduce

1. Auto-complete code with enter or tab FAST after the window pops up

首先，在不同速度下使用 Enter 和 Tab 重现 Visual Studio Code 中的补全行为，并在可用时使用列出的 Java 和扩展版本。比较快速和延迟的情况，并跟踪补全应用路径；完成的标准是应用补全后，光标右侧的括号、分号和所有代码都得到保留。
