Creating LEO constellation on Skydel issues

Hi everyone!! I have few questions about Skydel for LEO constellation, please… I would be happy if you can help!! Thanks!!
Question 1: TLE Import Error in Skydel
I am trying to create a LEO orbit by modifying a Galileo orbit and importing the corresponding TLE as a .txt file into Skydel. However, I keep encountering an error related to the first line of the TLE (specifically, the satellite ID). Could you clarify if Skydel requires a specific format for TLE files? If so, what modifications should I make to ensure compatibility?

Question 2: Increasing the Number of Satellites in a Constellation
By default, Skydel allows up to 36 satellites for the Galileo constellation. Is there a way to increase this limit and simulate a larger number of satellites within a given constellation?

Question 3: Unidentified Satellites in the Scenario
I have noticed that certain satellites (e.g., SV1) appear as “non-identified” in my scenario. This issue affects multiple satellites, not just SV1. What could be the cause of this, and how can I resolve it?
