Un-collapsed Sections in Published Doc Load

I’m not sure if it’s me or a bug but I have a doc in which a collapsed section just will not initially load collapsed. Maybe it’s a small thing but it’s annoying :wink: and I’m totally stumped.
I have set the header styles set sequentially ( H1 > H2), it’s correctly structured in the outline and I even have an almost identical section on the same page that DOES collapse as expected.


here is the published version of doc - Welcome to SAIC TRdb · SAIC Tools and Resource _aV3 (coda.io)
…and, if it’s helpful to know, it also renders this way for me in the editor when I open / refresh the doc
