Hi,  
I tried to load some sample data with squidpy, but the metadata file seems to be empty after loading (only nan).  
Why is that and how can I fix it?  
Thanks in advance.

I now realized that this is only true for some of the datasets provided by MERSCOPE ([MERSCOPE FFPE Solution Showcase](https://info.vizgen.com/ffpe-showcase)). I can read in the mouse liver dataset used in the vignette ([Vizgen Mouse Liver Squidpy Vignette — Squidpy main documentation](https://squidpy.readthedocs.io/en/stable/external_tutorials/tutorial_vizgen_mouse_liver.html)) but not the human liver data sample dataset from merscope with the squidpy.read.vizgen() function. Did anyone have this problem before and knows how to solve it?

Hi, I found the same with datasets provided by MERSCOPE ([MERSCOPE FFPE Solution Showcase](https://info.vizgen.com/ffpe-showcase)).  
How is it be possible to fix it?  
Thanks!
