[map query="post_type=projekt" overlay="true" shows only 10 pins

Hello,

I like to show all projects of a client. If i use the shortcut

[map query="post_type=projekt" overlay="true" show_images="false" show_posts="false" show_markers="false" zoom="8" center="48.80552,9.53994" height="500px" width="100%"]

then, there are only 10 pins shown, but 23 cpt projekt there. I checked the post's and the associated maps and can't see a difference why the pin is showing and why not.

If I use
[map query="all" overlay="true" show_images="false" show_posts="false" show_markers="false" zoom="8" center="48.80552,9.53994" height="500px" width="100%"]
all pins are shown. But I can't use query="all" when there are more cpt with maps.

Hope you understand what i mean.

Any help is much appreciated, thank you.
Rainer
