Affinity Designer: Pantone Conversion from .pdf, .eps, .ai

[p_q]

Hello.
When opening Illustrator files in Affinity Designer, i would like to keep the spot colors. If i open an Illustrator-.eps file in Affinity Designer, the Pantone color is automatically changed into cmyk. When opening an Illustrator-.ai or -.pdf file in Affinity Designer, the Pantone color is maintained as spot color. Does this have something to do with my color settings or is this a general problem with .eps files? 

Thanks in advance for advice.

As far as I recall, the issue lies with how Affinity applications deal with .eps files, both in and out.
