[juanpablo-santos]

Description:
Going from the list of tasks to any task and then to the launch screen we get this:

with the following js error message showing up on console:

Custom apps:
N/A, happens with every task

Steps to reproduce:
Happens if these two conditions are met:

• there are several platforms defined
• you get to the launch screen through tasks list -> task -> launch; if you create a task and then go to the launch screen you get the expected screen

Screenshots:
provided above.

Additional context:
Current workaround is to go to the Freetext section, where some predefined properties appear, and then back again to the Builder section, and we have our Builder screen back.
