Can not sync smartlist member

Hello everyone,

Step 1: I create a member with the name "Fitting & Installations" under the OPF_Direct Expenses and smartlist Expense Type with member selection is ILvl0Descendants(OPF_Direct Expenses):

Step 2: I rename the member "Fitting & Installations" to ""Fitting & Installation"

Step 3: I sync the smartlist:

but when i check the smartlist, the member does not change:

How can i sync the smartlist?

Thanks!
