Import and Export problems with special chars and fields

I have experienced some problems using the Import/Export template:

1 - When import from Spira, the special chars like "ç, á, ã" are lost in the Excel. A word like "integrações" become

"integraes" in the import.

2 - When import from Spira, the TYPE and IMPORTANCE fields are not imported, they become blank.

3 - New values added to fields of type list are not made available in the template and consequently are not possible to be uploaded. Example: I have added new possible value for requirement type, but in the Excel template it is not possible to select that new value and consequently to upload to Spira.
