Cannot search in Acrobat Reader DC (works in Chrome and Firefox)

File attached.

All text highlightable and copyable.

Acrobat Reader DC 2020.012.20043 on Windows 10.

Other pdfs work fine.

When I initially open the pdf:
If I search for 1234, it only matches the last 9 characters in each row (890123456). All 9 characters are highlighted (not just 1234). No other 1234 is matched/highlighted.

If I search for 5678, it says no results.

I tried disabling fast find:

If I search for 1234, it now matches and highlights the whole first page as one result, and the second page as the second result.

If I search for 5678, it finds and highlights each individual row (except for the last 9 characters).

If I open the pdf in Chrome, it works perfectly.

If I open the pdf in Firefox, it works perfectly.
