What exactly should be the correct behavior/interaction ?
When a creature with swampwalk or first strike is on the battlefield Urborg should, when selected, show a dialogue screen showing the following options; tap for mana, target creature loses swampwalk, target creature loses first strike. The latter two lasting until end of turn.

No.

As of CoRM15 mini3, the option "Remoeve ability" is now present in a mode selection popup when Urborg is clicked (regardless of whether a creature with swampwalk or first strike is on the battlefield or not), but when that ability is activated, the targeted creature does not lose first strike/swampwalk upon resolution.

Also, when a creature with swampwalk and first strike is targeted, the player is not prompted to choose whetehr that creature should lose first strike or swampwalk.
