dive editing issues

[Stephen Hemminger]

I have a couple of issues when trying to fix up dive information
like tanks and weights. These happen with the desktop version, haven't
tried with mobile but I would imagine the same thing happens.

1) Some downloaded dives ended up with multiple cylinders after
my attempts at editing cylinders and start/end pressure. It seems
the editing code gets confused and won't let me hit delete button.

Going in manually and removing the extra cylinders from the XML file
got rid of the issue, but obviously the GUI is a better place to handle it.

2) Unable to correct the weight values on some dives. After the dive
was created, with the wrong weight; I can't go in and fix the value in
the text box. Can enter new value, but it gets ignored.

Has this already been fixed?

Where would I go looking to see how to fix it? Where is this dialog
handled?
