Renaming upper-arm_girth with English gives error message

[Former user]

Changing the name attribute of the upper-arm_girth measurement in the indiviual_en-us.vit file from: <upper-arm_girth name="Оп" m_number="M52" value="0.0" gui_text="Обхват плеча" description="Номер размерного признака 28"/>

to: <upper-arm_girth name="upper-arm_girth" m_number="M52" value="0.0" gui_text="Обхват плеча" description="Номер размерного признака 28"/>

gives this error:

"Exception: Content of attribute name does not match its type definition: String content does not match pattern facet."
