ERC1155 Gas Fee seems higher than other free mints

Hi. I created an open edition for my projects’ holders for free but gas fee is relatively high when comparing other free mints via manifold. What is the reason behind it and how can I solve this problem, thank you. Contract Adress: 0xb7378aC226138f1B60216f57ce0DAf4c8E79Db15

Can you include a screenshot of the transaction and a link to the page?
