Explorer is displaying duplicated keys when extend from more than 1 models

Hi,

We are using Real Estate Core V4 Models in our Digital Twin, and we notice duplicated keys are displayed in explorer for this model: https://statics.teams.cdn.office.net/evergreen-assets/safelinks/1/atp-safelinks.html

This model is extended from two similar models, and they have some repeated fields.
The Explorer shows repeated keys, is this behaviour correct?

Thank you
