UEB Rule 8.5 deals with the Capitalised Passage Indicator. The rule tells us that the Capitals Passage Indicator sets capitals mode for the entire passage. Passage consists of three or more symbols-sequences and it may include non-alphabetic symbols. Passage is terminator by the capitals terminator immediately following the last affected symbols-sequence. In the example you provided, the capitals passage indicator should fall after the opening quotation mark and would then need to be terminated before the closing quotation mark. In this instance, the apostrophe does not terminate the effect of the capitals.
While a braille translation program is helpful, it is not something you can or should rely 100% on. In this instance, disregard what the translator is telling you, and follow what the rule says. 😊
