User can't re-join a team after she was removed from it

My question:
I am a team admin. Yesterday I removed a user (asaireddy@j… from the team (ePro…QA). Today I realized the user should still be a team member. I invited the user to join the same team again. When she tries to join it fails. She gets a “400” error and message:
"Your removal from team is still in progress. Please try after sometime. "

Details (like screenshots):
Here’s a picture of our current team composition.

How I found the problem:

Today I deleted the user’s invitation and created a new invitation, but the user still cannot join the team.
