618 + 2*16 = 713 -- it leaves room for the UP/DOWN scroll buttons

If you had your anchors set the second commit was probably comming from when you added your data type. Everytime you add a new dataType this also calls ZO_ScrollList_Commit.
Lua Code:
function ZO_ScrollList_AddDataType(self, typeId, templateName, height, setupCallback, hideCallback, dataTypeSelectSound, resetControlCallback)

And although I don't move any of the involved controls around after construction, somehow it doesn't get the correct height immediately. I guess it'll be safest to ZO_ScrollList_SetHeight explicitly to avoid any issues.

One of my scrollLists is set up just like yours it sounds, with both corners anchored & as soon as I dump the data in I call ZO_ScrollList_Commit on the next line without any delay. Mine doesn't have any problems like that though.
Are the controls you anchored it to from an addon? Any chance they moved or changed size which would have changed the placement of your anchors & changed the size of your scrollList ? Especially if one of those controls has something like ResizeToFitXXXX() and its contents or padding changed. Or someone set dimensions/position in XML, then reset it in lua and changed it by a small amount. It wouldn't take much of a change, those numbers aren't off by much.
