It's more worrying if it's only happened over the past few days, and you haven't actually changed or adjusted anything.
I can only suggest that if you have created an F1 2013 profile in the Logitech profiling software, that you don't use the auto-profile setting.
Perhaps select the 'Apply persistent profile' setting, or the the 'Do not apply profiles to games automatically' setting.
In the profiling software, this is under
Options > Global Profiler Settings
The persistent profile setting applies the same profile to all games (the same as having a global profile really)
The 'Do not apply profiles to games automatically' setting, means that you would have to select your F1 2013 profile before playing the game, as you might have many profiles for different games
I am only suggesting this in case your profiling software is having trouble sensing that you are running the game, especially if you tab in and out of the game. So your F1 2013 profile and the global profile are switching in and out.
This is pure guesswork.
Personally I always use the manual method, and manually select the profile I want to use before I run any of my racing games
PS If you need to get my attention you can tag me, as I only came across this by chance. A tag will generate an alert.
To tag, use the @ (ampersand) and type my name, a list of members will come up, more accurate choice the more your type. Like this
