Placeholder duplication in pptx

[bpffjl]

I'm trying to use a template to render a ppt, but am getting the error below.

Error in fortify_location.location_label(location, doc = x) : Placeholder "Content Placeholder 2" in the slide layout is duplicated. It needs to be unique. Calls: <Anonymous> ... fortify_location -> fortify_location.location_label

Looks like there is some issue with the name of a placeholder in the template. Does anyone have a good idea how to find the issue in the template? I went into the template to try to find the names of place holders, but didn't find any. Thoughts? Ideas?

You can find them by clicking the button where I draw a circle around in the following image:

They are displayed on the right panel.

An R solution is to look into the data returned by function layout_properties():

x <- read_pptx()
layout_properties(x)

Thanks so much!
