This is an indication of to much water. Is your soil draining or are the plants still in wet soil? If the ground does not dry and drain your bulbs could rot.
If you don't feel the soil will dry out, you can dig up the bulbs, clean them and store for next year. If they have begun to rot you will need to dispose of them.
