The generator does not operate below 300 Hz. And in the range from 300Hz to 100kHz, the frequency does not match the set one. Please help me solve the problem

Hello, greetings! I recently purchased a PC USB Oscilloscope device from Hantek, model 6074BD. However, there are some bugs in the equipment when used in DDS (Function Generator) mode. When asking the DDS to generate a frequency of 1Khz, its output always shows half of this value, 500 Hz.
I believe it is a software or firmware problem; Note: I am already using the latest version available on the website V. 2.2.7
Another important detail is that in the equipment manual it refers to a function generator output impedance of 50 ohms. However, when measuring the function generator output it does not present 50 ohms. This implies a voltage error programmed by the software, which instead of showing 3.5 volts peak to peak, shows 7 Volts peak to peak.
To solve this problem, an impedance selection option via software and internal relay in the equipment would be necessary.
That's it for the moment, I would like to know if there is a solution to my problem, any firmware or software update that can solve this problem!
Thanks
