Bhava chalit chart planets shifts backward

[avantika]

Hi,

When I look at my birth charts I see 3 planets shifts backward in Bhava chalit chart

Sun shifts from 6th Meena to 5th Kumbh
Saturn shifts from 10th Cancer to 9th Gemini
Jupiter shifts from 7th Aries to 6th Meena

Are those bad indications of losing strength. How will it effect me?

As per Rasi chart my planetry positions are
Jup 4 * 43' Mesha It shifts backward to Meena in Bhava Chalit chart
Ket 21 * 42' Mesha
Mar 66 * 32' Mithuna
Sat 92 * 34' Karkataka It shifts backward to Mithua in Bhava Chalit chart
Moo 190 * 50' Thula
Rah 201 * 42' Thula
Lag 203 * 40' Thula
Ven 310 * 57' Kumbh
Mer 321 * 47' Kumbh
Sun 334 * 40' Meena It shifts backward to Kumbh in Bhava Chalit chart

Also when using Lahiri ayamsa my navamsa lagna is Taurus. But when using chandrahari navamsa lagna is Aries. Which is the correct one?
