Baseline date governing successor activity date after removing the baseline

Hello,

I removed the assigned baseline from my schedule, and deleted the same in the maintaining baseline. Now my baseline is set as current project. But still shows some acitvities as per the old baseline in the gantt chart. This problem is occuring only with those activities which have actuals. (picture attached). when i link any successor it takes the date of the former bar shown in the gantt chart. what is the problem here?
