Converting from .h5Seurat to h5ad messes up observational metadata

[pakiessling]

SeuratDisk_0.0.0.9019 SeuratData_0.2.2 sp_1.5-0 SeuratObject_4.1.0 Seurat_4.1.1

I convert a rds to h5seurat and then h5ad.

I encountered the same problem on multiple datasets. Before: After:

The annotation column gets replaced by numbers maybe another column?

Any Idea?

relates to #138 probably the solution is similar
