A title and a screenshot isn't an acceptable solution. Provide a FULL and CLEAR explanation of the problem in your post and then summarise the issue in the title. Screenshots can provide additional information but should not be ALL the information. That said, your screenshot contains the answer to your question, so what exactly do you need us for?
My reading of SmarterASP.NET's various hosting offerings that you always get dedicated app pools and the different plans just gives you different amounts of memory. So either you are trying to run more than one app in one of your hosts, OR they goofed and put your app in with someone else's app in the same app pool, (or there is a bug somewhere in .NET Core 5.0).
