Moving to sd issue

[elnene20]

My issue is I am running out of space and decided to move all my apps to the sd card using TB. Okay once that was done all of the app icons that have been placed on the main screens dissapear after a boot up. Any one know why this is happening?

I went ahed and placed them all back to the main memory and know they stay where I put them. Some one please advise. Thank you
