Exclude non-existing values when calculating a number of allowed selected options

[Bellfalasch]

Content Studio 3.2.3

Using the following rules for an option-set, and removing an option that is selected stops the form for these options from being able to edit.

• Create an option-set, call one of the options anything, like "option 2"
• Use this config for the option-set:

<occurrences minimum="1" maximum="1"/>
<options minimum="0" maximum="1">

• create a content using this - "option 2" (or a part for that matter)
• update the xml and delete the option "option 2"
• loading any part or content having that option stored in the content data layer will get evaluated as already selected and all options will be unselectable.

Possible workarounds: change options to maximum=2 or re-add any deleted options that are used/stored in data.
