LoRa Unstable Ressource problem

The 2 of my LORA Models that i made "Liones Yelistratova from Hina Logi from Luck & Logic (SDXL Pony)" and "Heartbreaker Skin Reaper / Young Gabriel Reyes from Overwatch (Pony/SDXL)" are not working for generation as Unstable Ressources. So how can i make them Stable?
