Impress export to pdf - font name is changed

LO, Impress on Win7 pro 64bit.

Using Myriad Pro font. When I export to pdf (using pdf Options box) I get incorrect font look. Viewing font style in pdf it displays “DAAAAA+MyriadProBold”. If I remove the “DAAAAA+” prepend in the font style in a pdf editor (Soda PDF) it looks correct.

Font in Impress:
view in impress

Font in pdf:
view in pdf

Works correctly in ppt.
