How to fix wrong FTP value in "history" chart

Hi,
due to some very high pikes which have been picked up by my powermeter (50KW !) my Fenix5xplus detected a new FTP of 657 Watt or 7.08W/kg. I somehow must have exerted this wrong value. After deleting this activity, fixing the data with Fit File Repair Tool and uploading again with correct FTP of 239, the activity looks correct but if you go to 4 weeks chart it has still the 657 Watt, and it also shows this as actual value on the IOS version. I corrected the FTP setting on the Fenix as well, so my next ride will be correct again.
.

is there a way that I can "delete" the wrong value, or is the change picked automatically within the next 24 hours?

I have done that (FTP now set to 241W on my Edge 520) but I can't find a way to delete historical records of 400W....?

I love my new FTP of 1430 Watts and 18 W/Kg! I just contacted a pro team and asked them where my contract was. :-

The only way I could change my FTP was to perform a ftp test on my garmin edge 520 (goto my stats>ftp). I also enabled auto (ftp) calculation. Note you need to be wearing a chest HRM and have a connected power meter for it to work.

You should be able to change it on your Garmin device directly. Instructions for doing that would be in the manual for your device. For the 910XT it is in Mode > Settings > Bike Settings > [Bike] > Power Zones. For the 510 it is in Training Zones > Power.

This just happened to me today. Easy to fix User profile - Power Zones - cycling -FTP type in the correct value then sync and all should be good.;

But it is not the case :> This topic is about situation when NEW FTP has been detected during the ride and registered to GC...but has some crazy Value e.g because Power Meter was not calibrated correctly- or Power Meter has low battery level... in this case even when you want to ignore this new FTP after ride... it will not happened fully.

There should be some option in GC to exclude by FORCE unwanted treining from FTP statistics, as this wrong data are visible on historical FTP plots.
