Character style not closed

Question

Basic checks is reporting a problem "Character style not closed" on the following cross-reference in 1 Peter:

\x + \xo 5.13 \xt  Zk: Bbh 12.12, 25; 13.13; 15.37-39; Kls 4.10; 2 Tim 4.11; Flm 24 \x*

I can't see what is causing this, especially as there are already dozens of cross-references in the project with the same markers and which aren't generating errors, such as:

\x + \xo 5.6 \xt  Zk: Mty 23.12; Luk 14.11; 18.14 \x*

How do I resolve this please?

Answer 1

Without seeing more of the USFM and without seeing exactly where the check is flagging, my best guess is that the cross reference is inside another style that is not closed before the cross reference. If I recall, something like the following is invalid:
\em this is text\x + \xo 5.13 \xt Zk: Bbh 12.12,25\x* that is styled.\em*

The fix is to close the style before the cross reference and then reopen it afterwards:

\em this is text\em*\x + \xo 5.13 \xt Zk: Bbh 12.12,25\x*\em that is styled.\em*
