Tvheadend

I am loading the following XMLTV to tvheadend (through an internal grabber).

<?xml version="1.0" encoding="UTF-8"?>
<tv generator-info-name="test">
  <channel id="test">
    <display-name lang="en">test</display-name>
  </channel>
  <programme start="20181119000000 +0100" stop="20181119080000 +0100" channel="test">
    <title lang="en">SHOW A</title>
  </programme>
  <programme start="20181119060000 +0100" stop="20181120060000 +0100" channel="test">
    <title lang="en">SHOW B</title>
  </programme>
</tv>

Taking an eye on the xml data, we observed that there are 2 overlapping programs (from 06:00 to 08:00), show A and show B.

I totally agree that this should never happen, in any case my grabber gives it to me in this way.

What happens is that tvheadend only loads the show A (including the overlapped zone) but the B is never loaded, so there is an interval (in this case long) of channel without EPG. Would it be possible to adjust the times and load the Show B when there is no overlap already?
