I upgraded my SDG1025 to the latest firmware (1.01.01.39R7) from Siglent (available here). It seems to have fixed an annoying issue: the need to select the language each time it started.

Of note: the update process is straightforward, but initially I tried it using a freshly formatted 32GB USB flash drive and although it recognized the drive, it did not see the .ads file on it. I tried it with a very old (128MB) flash drive and it saw all the files on that drive and the update process went smoothly.

If Siglent ever releases new firmware for the SDG1025, I hope they will consider moving the very useful frequency counter feature selection to the top menu level (which has room for another choice on the soft keys). Right now, it takes 4 button presses to get to it which is excessive.
