A problem with list of subconfigs

Test case scenario
1 - Create a configuration in which a sub config exist. This sub-config has a list of questions, where each config is a sub-config

where Answer is a sub config itself. The thing is when we try to create a new sub-config of type Question, we first enter the title of the question, and then try to create a set of answers. If we try to save a created answer, we encounter the following error message:

The thing is this URL is called http://localhost:4502/content/website/main/_jcr_content.configData.json?configName=MainConfiguration/SubCONFIGURATION/Questions/answers&collection=true

However, the correct url should be
http://localhost:4502/content/website/main/_jcr_content.configData.json?configName=MainConfiguration/SubCONFIGURATION/Questions/q1/answers&collection=true
