After creating style it's not in 'load style' window

Hi,

I don’t know if this is normal or a bug, but: in Wirter I created 3 new styles. I can see them in the ‘style and format’ sidebar on the left, together with deafult styles. When I open ‘load styles’ window I don’t see in it those 3 styles I have just created. I’m wondering what is the reason for it.

Anyone has got an idea?

Thanks for any help.
