[MEI-L] showing change of mensuration in new section

Dear colleagues,
I cannot get changes of mensuration to show at the beginning of new sections. I am encoding 17th-century music in mensural style, putting <staff> and <layer> directly within <section> elements, and not using <measure> at all. I'm rendering with Verovio.
If I put the mensuration change inside a <scoreDef> within the <section>, no new mensuration shows at all. If I put <mensur> and <proport> elements directly into the <layer>, then it does show, but the proportion number is placed incorrectly (after or overlapping the first note). Example 1 below shows the scoreDef approach, and example 2 shows the layer approach. The first mensuration signature in this example should be "C3" and the second should be "cutC 3".
I will be grateful for any help you can provide, and my apologies if there is something I missed in the documentation.
Best,
Andrew
