It could be a legit bug that you need to submit an IT ticket for. But a couple of things I recommend when creating a custom Touring Plan:
- Make sure this button is unchecked if you are going to manually enter your LL times. Leaving it unchecked will keep things cleaner. TP will only use the times you manually configure and won’t try to assign you a LL.
- Make sure Force Use of Inputted Lightning Lane Return Times is checked. This is under Advanced Options, which is a section at the bottom that you may have to expand.
- Configure your return times using the Additional Scheduled Return Times section below the Advanced Options.
Hope that works!
