Saving new catalog with products features - features are not saved in XML file

Hi, Thx for the lib! Reading BMECat works great! I have some problems with creating files. I'm using version 4.5.0, I'm trying to create new catalog with my products and export it to XML BMECat file. I have problem because my features are not being saved to XML. Can You give me some example on how to create new catalog with features on products? Below I'm pasting some example of problem (with 1 feature but when i tried to save 33 features, non of them were saved), I've serialized Catalog to JSON for better visibility and the created XML BMECat. Thx!
