Can't display target compiled by maven

I updated idea by toolbox to 2020.3 on my Mac OS 11.0.1 (MacBook Pro 2018).The target folder disappear in the new version. The problem does not exist in win platform.

I've confirmed several related configurations below：

1. show option menu ->show excluded files : choose

2. preferences -> editor -> file types -> ignored files and folders: no target option

the target folder can be seen in the project folder
