User reported an issue with BB key filtering while using BTTask_RunEQSQuery. The filtering was inconsistent, sometimes filtering out keys of not matching type, sometimes not. User also reported selected key resetting, but that may be due to picking wrong key type.
User reported that commenting out CollectKeyFilters() in BTTask_RunEQSQuery removed the issue temporarily.
