In ArcGIS Pro stacked labelling options, 'space' always takes priority when choosing where to split the text regardless of whether another separator has the 'forced split' option turned on. This only matters if a maximum row count is set.
Anything with 'Forced split' should be prioritised over anything else.
If there is more than one 'Forced split' separator, I suggest using the list order to choose a preference.
See image for example.
