If my presumptions in the last message are correct, give the following a try for the regular expression:
and the following for the substitution:
\1 \2 level \4
Note 1: The above is only for the style you showed that includes Chinese characters with an optional "max" or "min" and "lv". It will not capture a simple lv followed by numbers. You should keep the earlier regular expression and substitution for those instances.
Note 2: The above regular expression presumes Python regex syntax. Since I know that NVDA add-ons are coded in Python I'm presuming this is the regex syntax NVDA would use. If not, then I would need to know which version of regex syntax is being used.
