Chris,
you have to test an SMPS electrolyt under WV for leakagide-current and check for ESR on switching(similar) HF _a simple capacitance measuring isn`t enough. As I see it on your pic; such caps are possible some humpbacked_to change...
Some times are rectifier OK in LV tester, but faild iunder Wvoltage.
