The bug is related to the use of Links section, on the upper right side of steemit.com interface when positioned in Feed. It is shown in the next screenshot:
When clicking on any of both links, My blog or My wallet, language settings switch automatically from English to Spanish. An animation of this bug is shown below:
Even worse, with Toggle Night Mode switched ON, it turns OFF arbitrarily (this in particular has already been reported by other users).
As a hint, my native language is Spanish but I use English as the interface language.
This bug occurs in Firefox Quantum web browser (v57.0.2 64-bit), in a Windows 10 Home Single Language Edition laptop.
I hope this can help to improve user experience.
Regards,
Fernando
