When you register a text string that is already registered, only the previously registered text is enabled. If the text string you register matches an existing text string, but the [Number of Characters] or [Number of Rows] is different, a new text string is registered.
If Text Table conversion reaches the maximum number of indexes to be registered, an error message appears, and only text up to that point is stored. The maximum number of indexes that can be registered varies depending on the device and whether or not [Expand index count] is selected. To select [Expand index count], from [Common Settings] menu, click [Text Table].
If you convert a text string, with its [Font Type] set to [Image Font], into a Text Table, the project size will increase.
