Exporting as SVG-missing elements

[Uxerist]

Hello people, 
I have a problem exporting a design to an svg file.
It is a group of elements that is used in several places, only the theme (colors, font, etc.) changes.
I use the group of elements throughout each design with the same arrangement of elements.
The problem is that the previous designs (groups of elements) are exported as I see them in the design, but when exporting the last design some elements are missing.
I recreated the missing elements, but the result is the same.
I also changed the layout of the elements but the result was the same.
There are no hidden elements.
Maybe it will become clearer when you see the pictures below.

The problem is in the logo.
I use 2 differents font for the logo. The letters have a few fills.
I've tried to use another fonts, the result is the same, the black circles disapear after exporting.
Still not fixed.

The objects should be there, but they do not have a fill applied. That is a bug with black fills.
