Strange Muban

While googleing for websites of the local government units, to add the weblinks into my XMLs as well as working through the village lists where I can find them, this respective list on the site of the TAO Kham Thale So (องค์การบริหารส่วนตำบลขามทะเลสอ), Kham Thale So district, Nakhon Ratchasima province, where I noticed something out of the normal.

The table read as following:

พื้นที่	หมู่ที่	จำนวนประชากร			จำนวน ครัวเรือน
		ชาย	หญิง	รวม
บ้ายขามทะเลสอ	1	231	233	464	120
บ้านหนองคู	2	78	67	145	92
บ้านสีจาน	3	4	5	9	8
บ้านหนองขุ่น	4	14	13	27	16
บ้านโคกแฝก	5	574	561	1,135	273
บ้านโคกสะออน	6	181	181	362	94
บ้านพวงพยอม	7	88	81	169	64
บ้านน้อยพัฒนา	8	143	148	291	71
บ้านบึงขามทะเลสอ	9	145	136	281	72
หมู่ 77		10	8	18	1
หมู่ 78		6	13	19	1
รวม		1,474	1,446	2,920	812

The strange thing in this table is not the low population number in village 3 and 4 - this is simply because those two villages (and also number 2 and 7) are partly covered by the municipality Kham Thale So (เทศบาลตำบลขามทะเลสอ), the strange thing are those two entries titled หมู่ 77 and หมู่ 78 (Village 77 and 78), each with one household. Both have no village number, but apparently aren't part of any of the other villages either. The village detail pages including maps don't have any details on these two entities, nor are they present in the Muban list from DOPA. And the above table is the only place on the website which mentions these two entities. So I have no idea what they are about.

Though I have not much hope to ever get any answer, I tried to raise this question in the forum of the website, which apart from a few spam postings seems to be dead.
