Edge 530: Configuration for Varia 511 can't be saved on Garmin Express

[Paredroi]

Today I discovered your Smart Bike Lights app and installed it on my Edge 530, which I have been using for years with my Varia 511.
First, I set Light Beam Activated to Timer Start as described in your instructions.
Then I tried these three configurations (where I have reduced/deleted more and more settings):

1,1!AUTO:1I[300]0###0,4096::1#2,2!BRAKE:1:4:0:0A[-20!:1:0:0:0D=1##2:Varia 511!OFF:0!ON:4#0::#0:1#0#0#B3121##7#0#0

1,1!AUTO:1I[300]0###0,4096::1#1,1!:1:0:0:0D=1##2:Varia 511!Off:0!Solid:4#0::#0:1#0#0#B3121##7#0#0

###0,4096::1#1,1!:1:0:0:0D=1##2:Varia 511!Off:0!Solid:4#0::#0:1#0#0#B3121##7#0#0

But none of them could be saved in Garmin Express, see GIF below:

Do you have any idea why this might be the case and what else I could try?
Thanks in advance for your answer and your great tool!

It seems like that something broke with the latest Garmin Express as I have the same issue as you. Unfortunately, I cannot do anything about that. Try to use Garmin mobile app to change the settings until Garmin fixes the issue.
