FAQ: Why is Runtime Word Segmentation not segmenting my text properly?
Experiment Builder can automatically create Interest Areas around at certain points in the text at runtime if the "Use Runtime Word Segment Interest Area" property of a Text Resource or Multi-line Text Resource is checked.
This is the bottom-most property in the Properties Panel for a text resource.


The default behavior for this option is to create an Interest Area at runtime around each word individually (using space characters as the boundaries for the Interest Areas). To change this setting, go to the "Edit menu -> Preferences ->Built-in Interest Area Preference -> WORD_SEGMENT” . Most issues with word segmentation can be resolved by adjusting these settings.
