You are wrongly using the STRING(REPLACE …) command.
The right way to use it to avoid list conversion is to expand the list inside
quotes (to preserve list items separators):
STRING (REPLACE "../" "" SIMPLE_LIST "${SIMPLE_LIST}")
Without the quotes, all list elements are concatenated in the result string
(see documentation).
Another possibility is using LIST(TRANSFORM …):
LIST(TRANSFORM SIMPLE_LIST REPLACE « ^\\.\\./" "")
