Narrative:
The FMS-stored route for XXXDAL01 includes the glen rose arrival; including coming over the top of dfw; and the last two fixes are hurbs and [runway] 13R. However; this is problematic for several reasons. First; the glen rose arrival doesn't allow a turn direct to [runway] 13R after hurbs intersection. Second; this stored flight plan does not include isabl at 11;000; it must be entered by the pilot. But if; after being entered; the pilots change runways to [runway] 13L; the isabl 11;000 restriction will drop out. So; even after having verified the crossing points; it is possible for this restriction to drop out if the runway is changed; causing a violation; and possible separation. (Note: this did not occur on this flight. Everything went normal because of my awareness of the situation. I am just reporting this for safety awareness because I believe it is a problem; since I have encountered it in the past; and have filed an as soon as possible in the past on the issue.
