Odd "1" appearing in figure caption in LaTeX

[APEXCalculus]

Figure 11.3.16 has an errant "1" that appears in the caption.

In the PreTeXt, line 1022 of sec_dot_product.ptx contains the line

<caption>Sketching the three vectors in <xref ref="ex_dotp4_part1" text="local">Part</xref> of <xref ref="ex_dotp4"/></caption>.

In LaTeX, this produces the caption-creation of

\begin{figureptx}{Figure}{Sketching the three vectors in \hyperlink{ex_dotp4_part1}{Part~1} of \hyperref[ex_dotp4]{Example~{\xreffont\ref{ex_dotp4}}}}{fig_dotp4a}{}%.

The image below shows the extra 1. to the left of the word "Figure"; I changed the caption to a simple "Hello" to see if that would fix the problem; it obviously didn't.

What is causing this?

I don't see this in the most recent PDF builds that I've done. Did you move this figure at all in any of the work you have open right now?

Here is that example in HTML and here is a screenshot of it from the last PDF build I did:

Did you move the figure to the beginning? I am wondering if that 1 is coming from a list environment.

[sean-fitzpatrick]

Oh! Yes, in #447 it looks like you made the image the very first thing in the first list item.

We are hijacking some fairly delicate XSL to get figures into the margin, so I can't say if this is a PreTeXt bug, or if it's caused by the overrides I'm applying to get the layout we want.

I assume the goal is to move the image onto the previous page. My suggestion:

• End the first paragraph immediately after the display math
• Consider making the display math a single line? It should all fit on one line
• Put the image right after the display math
• Open a new paragraph after

Like this:

<p>
      Applying <xref ref="def_orthogonal_projection"/>, we have
      <md>
        <mrow>\proj uv \amp = \frac{\dotp uv}{\dotp vv}\vec v</mrow>
        <mrow>\amp = \frac{-5}{10}\la 3,1\ra</mrow>
        <mrow>\amp = \la -\frac32,-\frac12\ra</mrow>
      </md>.
</p>

IMAGE GOES HERE

<p>
      Vectors <m>\vec u</m>, <m>\vec v</m> and
      <m>\proj uv</m> are sketched in <xref ref="fig_dotp4a"/>.
      Note how the projection is parallel to <m>\vec v</m>;
      that is, it lies on the same line through the origin as <m>\vec v</m>,
      although it points in the opposite direction.
      That is because the angle between <m>\vec u</m> and <m>\vec v</m> is obtuse (<ie/>, greater than <m>90^\circ</m>).
