Update/Change Trak PlayList titles doesn't work

I am trying to Change/Update a Trak playlist title and it does nothing no cionfigmation no error

Steps I go to
Account -->
Personal List -->
Enter on the list I want to change the title -->
Click on pencil -->
Change the Title -->
Click on the Update label

but nothing happen

So I changed my playlist titles directly in Trakt it was sussesfull but movie base does not get the update

wondering if is there a problem with trak

I check my two legacy Apps adn they got the update
