Errors in CLEC

I have searched the database of CLEC and read the concordance lines sorted by Wordsmith. But alas......there are a lot of tagging errors in this corpus.
I believe this will affect the validity of the research results, particularly for error analysis.
Did anyone notice this serious problem?
I have found many errors in CLEC and tried to make a summary. it is not completed yet. i will finish it as soon as possible. if you find any errors which are not listed in my post yet, please point out.
you can refer to my previous post here:
