That row looks well but the relevance is really long and causes crashes on Android 4 (using newer versions everything may work well).
I tested your form with a small change: S_21836_eng_v3.xlsx (37.3 KB)
I was able to reproduce the issue using your form and Android 4.1.2. Then I split your long relevance into three parts and it works well. So you can use it as a workaround.
I also reported an issue to gather more info whether we can fix the problem: https://github.com/opendatakit/javarosa/issues/355
