Bug: When inviting friends to join the group, the displayed number of selected people is incorrect

[DreamerXXT]

What happened?

When inviting friends to join the group, the displayed number of selected people is incorrect

What did you expect to happen?

1. Correctly display people who have joined the group in the friend list
2. When a friend who has not been selected and wants to be included in the group, the correct number of selected people will be displayed
3. Can confirm invitation

How can we reproduce it (as minimally and precisely as possible)?

1. Enter a group
2. Click Add to invite friends to join the group
3. Observing people who have already joined the group and those who have not joined the group
4. Select a friend who is not in the group
5. Observe the display of the selected number of people

Anything else we need to know?
