Duplicated the variant "Landing page default" when i try to Modify it, it throws an error "failed to save page"

 

I tried to change the name from "Overview" to "Admin landing page" but its not getting saved . If i try to update the same in  "sys_ux_macroponent" table it works , but its not getting saved on ui builder
