This is working by design - It's recommended to use either the Clarity Gantt or MSP for scheduling for a project, but not both the Clarity Tasks section/Gantt and MSP, to avoid issues such as the dates changing unexpectedly.
If the prior dates of the tasks were set to the project start date in Clarity, the symptoms may seem that old project data is being pulled up / prior version of the schedule is being loaded instead of the current schedule from Clarity being pulled in, but the root cause is the same in that case if no constraints, dependencies, etc are set.
