Hi,

{ c'1-"p" }

is a shortcut for

{ c'1-\markup { "p" } }

both a TextScript.
Primarely, the direction to place the markup is done looking at
TextScripts 'direction property. Default is DOWN.
If the TextScript is prepended with a dash "-" the default is taken.
This may be changed by using other direction-indicators like "^" or "_".
Obviously "_" is the default, but look at the following to see its usage:

{ \voiceOne c'1-"p" c'1_"p" }

Here the default was changed already by \voiceOne. Ofcourse it can be
modified as shown.

Fingerings are indications, which finger to use.
For the guitar it means, which finger should be placed on the fret.
The direction is calculated by a procedure: ly:script-interface::calc-direction
But can be changed using direction-indicators or by setting
fingeringOrientations

{ c'1-1 c'1_1 }

For the guitar printing StrokeFinger is often needed/wanted.
>From NR:

{
  \clef "treble_8"
  c4\rightHandFinger #1
  e\rightHandFinger #2
  g\rightHandFinger #3
  c'\rightHandFinger #4
  <c\rightHandFinger #1 e\rightHandFinger #2
   g\rightHandFinger #3 c'\rightHandFinger #4 >1
}

The default is to place them to the right of the note.
But can be changed using direction-indicators or by setting
strokeFingerOrientations.

{
  \clef "treble_8"
  c4_\rightHandFinger #1
  c4^\rightHandFinger #1
}

The quite verbose \rightHandFinger #1 can be shortened as already
shown in this thread.
Let me quote NR again:

#(define RH rightHandFinger)

\relative c {
  \clef "treble_8"

  \set strokeFingerOrientations = #'(up down)
  <c-\RH #1 e-\RH #2 g-\RH #3 c-\RH #4 >4

  \set strokeFingerOrientations = #'(up right down)
  <c-\RH #1 e-\RH #2 g-\RH #3 c-\RH #4 >4

  \set strokeFingerOrientations = #'(left)
  <c-\RH #1 e-\RH #2 g-\RH #3 c-\RH #4 >2
}

In every case prepending a post-event with "-" means, let LilyPond
choose where to print.
This can be set/overridden in various mannors.

Soooooo, I've not the slightest idea where you see
errors/mistakes/faulty behaviour here.
