Transparency behind Transparency

Support Basics & Interface

I have the following problem:

I have a bottle with a label, and on this label i have a alpha map, so some parts of it are invisible. This is functioning well but every transparent thing i see trough the bottle is black.
I use Yafray for rendering.
The bottles material is the presetting “clear glass”
here an example(red lines added afterwards to border the 100% alpha plane i added for testing):

I think, you have to increase Ray-Depth of the materials to render transparent things arranged in a “batch”.
