problem with guide on moved iptv channels

[whichway]

I am on 4.2.2

I get my guide info correctly on the iptv channels UNLESS I move one of them. In that case I lose the correct,
xmltv file address and therefore lose the guide data.

Unmoved channel for epg source
source: xmltv
xmltv file: http://ip address:ip port/xmltv.php?username="username"&password="password"&type=m3u_plus&output=ts
mapping: "channel name"

However on a moved channel for epg source I have
source: xmltv
xmltv file: http://ip address:ip port/xmltv.php?username="username"&&password="password"&&type=m3u_plus&&output=ts
mapping: BLANK with no drop down options to choose

If you notice because the channel was moved (either by changing the base number or the sub number) you generate double (2) & between each control pharse.
I tried to edit the "xmltv file" name line back to what I know is the correct statement for that line but the program will not take it and just changes it back to the incorrect
statement of the ip location it started with. I tried to use the browse function to have it look in a data set to find the correct statement but I could not get that to
work either.

Please help fixing this annoying problem
