Picky SGF format

[DiLollipop]

Love the app and created an account just to bring it up. What format does app like sgf?
For example (github won't allow .sgf and guest pc won't allow changing to .txt):

(;AB[ab][ad][af][bf][ca][cb][cc][cd][ce][cf]AW[ae][ba][bb][bc][bd][be]C[Cho elementary problem 5])
Displays as a full 19x19 board and problem in thumbnail; when I open the problem it shows a blank board.

(;AB[be][cc][cd][cf][eb][ec]AW[bb][bc][bd][cb][db]C[GKshumo problem 3])
Displays off a few lines on the thumbnail and a blank board when opened.

(;GM[1]FF[3]AW[ro][qp][rp][qq][pr][qr]
AB[qm][rn][po][qo][pp][nq][pq][or][os];B[rr];W[rs];B[sq];W[ps];B[ss])
Shows up great in thumbnail and when opened shows only the solution!

(;FF[4]GM[1]SZ[19]AP[SGFC:1.17]C[Cho Chikun's Encyclopedia of Life & Death (Vol 1)]
(;AB[be][bf][cb][cc][cd][eb]AW[ad][ba][bb][bc][bd]C[problem 1]
))
Doesn't show comment but everything else perfect.

All of these problems show up ok in GoGrinder or Hactar Go but go grinder won't do game collections, pick tsumego or thumbnails, Hactar Go I haven't figured out the file collection and how to disable annoying animations or intrusive variation buttons. Also, I know the app can't find a solution, I cannot practically add solutions to all the collections and don't need the sad reminder I can't be applauded every. single. problem.
Does Gobandroid really like FF[4] files? Maybe I just need to get good at editing.

A last issue is burnt in text scroll for a commented game, e.g. scrolling down on a comment displays one stationary comment and one moving comment overlapped but that it more hit or miss.
