Multiselect - form.load issues

When using the multiselect form type, if I have two items to select in my database things work fine. For example if I have a data set of 15,9 for a column in my database it will select the options with vaules of 15 and 9 in the multiselect. However, if I only have ONE integer in my data set, either 15 OR 9, no comma, no multiple data, the multiselect will not pre-select that option with the value of 15 or 9 by itself.

Break down of what I mean.

tech_id in my database shows 15,9
When I load the client profile it will select the tech names associated with id’s 15 and 9.
This is GOOD… this is what I want.

HOWEVER

if a profile does not have two technicians, things go wrong.

tech_id in my database shows 9
When I load the client profile, it will not select the option with the value of 9… it doesn’t select anything at all.

Any suggestions?

Problem seems to be fixed in 4.13 release.
Sorry, I posted before I updated.
