4 houses in 2 signs... Why?

So I was just wondering, Why do I have 4 of my houses in two of the same sign. I have not noticed on others charts if they have this, but why do I. What does it mean?

1st house is Scorpio

2nd house is Sagittarius

3rd house is Capricorn

4th house is Capricorn

5th house is Aquarius

6th house is Pisces

7th house is Taurus

8th house is Gemini

9th house is Cancer

10th house is Cancer

11th house is Leo

12th house is Virgo

Please explain or help me understand?

It's called duplicated signs.

Inversely, you're missing Aries and Libra in the house cusps, that's called intercepted signs.

I have the same.

As @Gem_from_Venus says, is common in those cases, that's why some astrologers use other house systems as Vehlow or equal house system... to "correct" that
