Use wildcard in locator and get incorrect textcontents

I am using silk4j 19.5 and recording on Chrome 71

I noticed the followings assertion always fail when I use "*" in the locator.  I used object spy to dectected this specific object locator. It is "//BrowserApplication[2]//BrowserWindow//DIV[@textContents='-']".   It returns "OUTR" instead of "-" when I use * in the locator, I checked object tree and checked on the UI, there is no such object containing "OUTR" as textcontents. Anyone has any idea?

DomElement combidLoc = desktop.<DomElement>find("//BrowserApplication[2]//BrowserWindow//DIV[@textContents='*']");

Assert.assertEquals("-", combidLoc.getProperty("textContents"));

Thanks
