Updating requirements imported from DOORS overwriting requirement object type in Matlab 2025b

Hi,

I have a Simulink project originally created in Matlab 2023a that has a requirements module of requirements imported from DOORS. When originally imported from DOORS all the requirements were set to type Functional but as I also imported headings and information statements I went through them all in the Requirements Editor and set the headings to type Container. Previously when changes were made in the DOORS module I would use the Update function in the Requirements Editor on the Import object and any DOORS changes were pulled in correctly but the manual changes I had made to the requirement types were not overwritten.

Now that I have upgraded to 2025b I have found that when I do an Update now all the requirements are set back to Functional regardless of whether I have changed them. This causes me a real problem as then all my metrics for Implementation and Verification coverage show lots of uncovered requirements as it includes all the headings.

Is this a known/deliberate change in behaviour in 2025b and is there any way I can stop it happening?

Many Thanks.
