it's not completed. In the pub. status it is said that the series are completed but it's not, chapters are not translated yet or missing, so it's not complete.
'Pub. status' stands for 'publication status' and refers to whether or not the original publication of this manga has ended or not. Its not meant to show whether or not all of them are translated.
Could we perhaps have a different field for whether or not the scanlation has been completed or not? Besides the [END] tags, that are usually used on the last chapter?
