Are you using "change like draw tool" when converting those entities? If you just use change properties and change the fill, you won't get that automatically, but if you use the change like draw tool command instead (found by right clicking change properties) it sets up things correctly.

As an alternative, you can also set up an outer glow using effects, that can often give a neater result (but not the exact same though)

Dragging and dropping an image into CC3+ is the equivalent of doing a Draw -> insert image, but it skips the dialog box. Unfortunately, this also means it skips the dialog where you can turn off the border, and uses the default which is applying a border to inserted images.

You can turn this off by using :CC2EDIT: on the images, and turn on the hide outline option. Unfortunately, this can only be used on one image at a time (Don't worry about the purple selection rectangle this operation seems to leave behind, that goes away the next time you select something else)

The better way to insert symbols to avoid this in the first place is to do as Raiko suggested, and use the :ICON_CATALOG: button and browse for your folder. This will show all the images in that folder in the symbol catalog window, and you can insert them the same way as regular symbols.

If this is symbols you are going to use often, the even better option is to make proper CC3+ symbol catalogs for them. This allows you to set up scaling and things correctly in the symbols themselves, so you don't have to re-scale every image inserted, among other things.

Personally, I think you are using too fancy a font for those smaller labels. Fancy fonts are difficult to read and look cluttered easily, even if they are thematic. I would recommend sticking with simple fonts for those.

You may also wish to try some color differences to isolate those larger area-spanning labels from the others.

Wyverns maps are now to be found in the atlas:

Which one you should have doesn't just depend on the number of add-ons/annuals, but which ones specifically. Not every style installs a file there, even if it would have made sense to have it, but it is a manual process making these in the first place, and I suspect they are often overlooked.

Here's the list of my files. I've got absolutely everything installed. You can check with my list and see if there is anything missing that you think you should have depending on your installed products. (The CSUAC, Bogie, Digital marked ones comes from the community symbol packs, and are not standard PF files.)
