i have an issue with the slide title/base layer title. My colleague created 4 different engages for us to use in our courses. He renamed the base layer title (1 in the picture). Now when you change the slide title (2 - from master slide layout) it does not syncronise the slide title with the base layer title. Seems like they are not connected anymore.
I already tried to reset the layout and change the layout to an other one and back, both didn´t work. I don´t want to copy the engages to a new slide, because there are many triggers and layers on them.
