Sitemap problems

Hello First of all thank you for this plugin. I write requesting help for the following: I have a site that has been in maintenance status for several months with its plugin. Now that I activate it, in search console the sitemap does not support me. (obviously after disabling your plugin) I suspect that your plugin has left a trace of code or something similar, which prevents indexing the sitemap in search console. Because the suspicion? Because comparing with 7 other sites that I have installed in this month, the only one that failed is the one that was in maintenance with its plugin. I am an ignorant in this code, but I would appreciate it if I had my request to leave the doubt and see what I do. regards
