Sure it is not! Problem is, entry for Serbia was not exist in original db.txt

I added 60G data as per regulatory document; but then missed data
for 2.4/5 bands leads to this problem...

By the way, same problem is for AD (Andorra)

Correct solution would be, as you mentioned below, to add data for Serbia.
I'm not sure what is correct rule set.
Most of ETSI countries (but not all!) have rule set like this:

country AT: DFS-ETSI
	(2402 - 2482 @ 40), (N/A, 20)
	(5170 - 5250 @ 40), (N/A, 20)
	(5250 - 5330 @ 40), (N/A, 20), DFS
	(5490 - 5710 @ 40), (N/A, 27), DFS
        # 60 gHz band channels 1-4, ref: Etsi En 302 567
        (57240 - 65880 @ 2160), (N/A, 40), NO-OUTDOOR

I am not sure we can apply this for Andorra and Serbia since I see exceptions -
some ETSI countries have different rules. See BG, CZ, DE, GE, NL, TR, UA.
