Hi,
I recently responded to a similar query (by another individual) on this portal/platform. In your case, Ascendent or Udaya Lagna seems to be placed in the Zodiac sign of Capricorn or Makara Rashi (as per the birth-chart I have cast), with Lagna Lord being Vakra/Retrograde and placed right behind.
Moon/Chandra is placed in the Zodiac sign of Libra or Tula Rashi, Venus/Shukra is placed in the Zodiac sign of Leo or Simha Rashi alongside Mars/Kuja.
So, Mars/Kuja is placed in the 7th Bhava / 8th house from Ascendent or Udaya Lagna, 11th Bhava / 11th house from Moon/Chandra and closely conjunct Venus/Shukra. Placement of Mars/Kuja in 1st, 2nd, 4th, 7th, 8th and 12H from Udaya Lagna, Moon/Chandra and some folk consider Venus/Shukra, to qualify a birth-chart as being Mangalik.
In my humble opinion, the so called cancellations and exceptions do not exist. As one of my other learned friend (who has a Uccha or exalted Mars/Kuja and a powerfully strong Ruchaka Maha-Purusha Yoga always says and I quote, “If a Uccha or exalted Yogakaraka Mars/Kuja does not spare a native, then it is safe to assume he does not spare others”.
Take care…
