There is this bug that seem similar

http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=1756

But it does not seem to solve my problem. The hidden field does not hide what
it should hide. The first problem is the documentation which is simply
illogical if it's a simple bitfield:

---------------------------------------
9 => Future use
-8 => Flag
-7 => OPAC !Intranet !Editor Collapsed
-6 => OPAC Intranet !Editor !Collapsed
-5 => OPAC Intranet !Editor Collapsed
-4 => OPAC !Intranet !Editor !Collapsed
-3 => OPAC !Intranet Editor Collapsed
-2 => OPAC !Intranet Editor !Collapsed
-1 => OPAC Intranet Editor Collapsed
0 => OPAC Intranet Editor !Collapsed
1 => !OPAC Intranet Editor Collapsed
2 => !OPAC !Intranet Editor !Collapsed
3 => !OPAC !Intranet Editor Collapsed
4 => !OPAC Intranet Editor !Collapsed
5 => !OPAC !Intranet !Editor Collapsed
6 => !OPAC Intranet !Editor !Collapsed
7 => !OPAC Intranet !Editor Collapsed
8 => !OPAC !Intranet !Editor !Collapsed
9 => Future use
---------------------------------------

If you try to find the binary pattern in this you will not be able to do it.
For example, I found that the 3rd bit ( value 4 ) trigers the display in the
editor. According to the table above, 4 does not trigger it, but 5 does. But 5
is a combination of 4 and 1, so if 5 does, than 4 should block it too since 1
since used for collapsing.

According to my tests:

Bit 1 (value 1): Trigger the collapsing
Bit 2 (value 2): does nothing
Bit 3 (value 4): Hide the field from the editor
Bit 4 (value 8): does nothing
Sign Bit (+/-): does nothing

Which leave the following options not working:
Hide in OPAC
Hide in Intranet

I tried it with field 590 and field 300 which both are shown in OPAC and
intranet.

I was wondering if there could be something else that could override the the
hidden field.
