Hello
From your screenshot I could observe that there is 140 on stock and there is no requirement for this material, therefore, MRP should not create any replenishment proposal.
Try to add a safety stock on the material master or try to create some PIRs (more than 140), so that there is a requirement to be covered by MRP.
If system generates planned orders instead of delivery schedules, check the following note:
