When in approach phase moment you hit TOGA FMGC goes to GA phase. In GA phase CLB mode is not available also it does not do any predictions. Simply changing lateral mode to NAV will not give you constraint protection. You need to get out of GA mode by activating approach only then you can get CLB and subsequent constraints protection.
