Radio Times INI File shows strange Characters in Title.

Apologises, if this is the wrong forum to log this query.

I have just started to use WebGrab++ so am quite naive about it.

My WebGrab++.config.xml is using the radiotimes.com for channel informaiton, e.g.:

<channel update="i" site="radiotimes.com" site_id="94" xmltv_id="BBC One London">BBC One London</channel>

The listing is being grabbed and made into an xmltv file, but the data in the Title element seems to have extra text (the same for every program:

<programme start="20160629134500 +0100" stop="20160629180000 +0100" channel="BBC One London">
    <title lang="en">Wimbledon 2016"}, (?)</title>

I have a couple of questions:

1. Which file should be used to try to remove this extra data:
   1. radiotimes.com.index-only.ini
   2. radiotimes.com.ini
   3. radiotimes.com.xmltv.ini
2. Would the command (I am not sure what scripting language is used in the .ini files) be; title.modify {remove(type=string)| '"}, (?)'

Any help would be really useful.

Thank you.
