Landscape masks re-use identical portions / overlap of masks

The new Landscape mask feature is a brilliant addition, filling a long-standing gap. In many cases, it works beautifully and creates separate masks as expected.

However, there is one major shortfall or bug: it often creates overlapping masks, re-using the same portions of the photo for multiple unrelated masks. I can see how "mountains" and "vegetation" overlap and be used in both masks, but "water" should not be re-used for "sky" or "mountains" or "ground". Water is water, it is neither of the others. I attached an example where it not only fails to detect the sky (it detects it as Mountains - but excludes the Milky Way) and then uses that same sky portion in the "natural ground" mask. The "water" mask includes the Milky Way in the sky, even though there is a fairly clear horizon line. The latter is clearly a failure of A.I., but in general, masks should not overlap and should programmatically be exclusive of each other (perhaps with the exception of mountains and vegetation).
