direct dial folder not working

[MotoDroid2010]

I have setup a folder on my home screen for my direct dial contacts. The folder has stopped working twice - i.e. nothing happens when I tap the folder icon. This has happened before and I had to just delete the folder, re-create the folder and manually add my direct dial contacts one by one.

1) Is there any way to fix this?

2) Why is this happening and is there any way stop it from recurring. It is very time consuming and annoying to add all the contacts over and over again.

Any help would be greatly appreciated. Thanks.
