Trainer difficulty setting across multiple profiles

My husband and I both use Zwift on the same PC, with our own profiles. When one of us changes the trainer difficulty setting, it then also changes it in the other person’s profile too. Is this correct?! I am having to remember to go into the settings to change it every time?

We are very different height/weight and fitness and so it is a bit frustrating to have started a ride and then wonder why it is feeling so difficult, only to find that my trainer difficulty has gone up to 100% as my husband had increased his for his previous ride.
