Text fields do not save members information

Hi,

I add some new text fields in form. When member does new registration – fill the fields, after in his profile theres nothing, instead of information there is only “Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array,Array”
What’s the problem? In settings I filled only a title of the field, nothing else.

Thanks
