PackURL in .uvprojx is chaning from https to http

We are a team of developers working with MDK uVision 5.36.0.0.

In the project file the packURL content is changing constantly between a http and https link depending on who is checking in the project file

Example:

  • <PackURL>http://www.keil.com/pack/</PackURL>
  • <PackURL>https://www.keil.com/pack/</PackURL>

We could not find any IDE settings which influences this behaviour.

What IDE or project settings need to be adapted so that all developers use the same PackURL links?
