To Reproduce
Steps to reproduce the behavior:

from arcgis.map import Map

## NOTES: GroupLayer is at index 1.

agol = GIS("home")

wm_item = agol.content.get("WM_ITEM_ID")

webmap = Map(wm_item)

gl = webmap.content.layers[1]

# Rename Layer in GroupLayer (well, attemp to anyway)
gl.update_layer(
    index = 0,
    options = {"title" : "Special Protected Areas (SPA)"}
)

gl.update_layer(
    index = 1,
    options = {"title" : "Special Areas of Conservation (SAC)"}
)

webmap.update()
