Cannot beat a good receiver made in the UK, Japan or USA, we get what we pay for as far as Chinese junk is concerned. 
The Taiwanese made good stuff, also. My Sangeans made in Taiwan all are still working well. Only one (my DX-398/Sangean 909) had a negative battery terminal go intermittent (from hard use, after about 8-9 years) -- an easy fix.
Otherwise, your point is very well taken. The Japanese made excellent radios and aside from ham rigs, I don't think any DX radios are made in Japan anymore, aside from the Sony EX5MK2 AM-FM radio (a MWDXer with synch). And maybe some other model I don't know of...
The Chinese make simpler radios OK (the Sangean PR-series seem to hold up well), but the more complex you want from the radio, at a low price, you get varying quality apparently. My Grundig G2 is still working OK (it gets weekly or 2x a week use), but I"ve read so many complaints about dud Tecsuns/Kaitos/Degens that I think it's a matter of the company telling the factory to churn 'em out as inexpensively as practical....
As far as the OP is concerned, if I were in your shoes I would see if it could be returned/replaced... or just live with the glitch. As long as it receives well. Every radio seems to have some idiosyncrasy that one has to live with... it's just too bad in your case it's a defective form of idiosyncrasy. :-)
