Textures skins and mash up packs showing as not purchased

I had several packages of skins textures and mash ups that used to work on my xbox one, show as not purchased. Some were purchased on the xbox 360, but transferred to the xbox one edition, and I had installed and used them used a year ago after the change from xbox one edition to the newer minecraft. The skyrim pack is asking me to buy it again which I have owned since the 360 edition used in one edition and it worked on the current minecraft and store playable on xbox one in 2019, and I purchased the mythology package with norse, Greek, Egyptian and Chinese mythology mash ups in august 2019 (was able to use all my old purchases including skyrim then as well) but now none of those purchases are showing in the current minecraft edition on xbox.
