What version did you upgrade from?

I have a file with this at the top:

It impossible to tell what's wrong with just that information. Can you
share a minimum working example that demonstrates this? (something that
should probably tangle 3 files but is instead tangling just 1?)

My best guess is you have this style of  incompatible properties?

*** Old Babel header properties are no longer supported

Using header arguments as property names is no longer possible. As
such, the following

#+BEGIN_EXAMPLE
,* Headline
:PROPERTIES:
:exports: code
:var: a=1 b=2
:var+: c=3
:END:
#+END_EXAMPLE

should be written instead

#+BEGIN_EXAMPLE
,* Headline
:PROPERTIES:
:header-args: :exports code
:header-args+: :var a=1 b=2
:header-args+: :var c=3
:END:
#+END_EXAMPLE

Please note that, however, old properties were defined at the source
block definition. Current ones are defined where the block is called.
