IXBRL in Companies House generated accounts


For company 09178757, the accounts made up to 31 Aug 2019 filed on 08 Jul 2020 show a negative figure for “Capital and reserves” in the human-readable document, but the embedded iXBRL data does not mark the figure as negative with the usual sign="-" attribute.

These accounts appear to have been filed using Web Filing, given the “Companies House WebFiling - Micro-entity Accounts Form” generator tag contained in the iXBRL, so I wanted to check if this is user error, or more likely since the human-readable version is correctly displayed, if this is an error at Companies House.

I appreciate that as a registrar, CH can only display the information filed by companies, but in this case, it would appear that CH itself generated the document which contains the error.

Apologies if this isn’t the correct forum to raise this query - if not, I’d be grateful if you could point me in the right direction.

Many thanks.
