Bolts that delete in the creation tree (SW assembly)

Hi all!

I have a small problem when I insert toolbox bolts in Solidworks 2014,  when I am done, I save as usual and then close. The next day, when I open the assembly again, the toolbox items have all been removed from the creation tree and I have to right-click on them and undelete them so that they reappear. In this entire process, Solidworks never gives an  error message. How can this problem be solved?

Thank you for your help and have a good day!

If solidworks does not give error messages, it is because you must have disabled them unintentionally.

Is the toolbox loaded when the assembly is opened?
