I think there must be a big problem with my settings. I have tried a lot of checks and learned a lot of references, but I can't find the reason. I really need your help！
I set the bid method of Google Ads as target cost per conversion, and also set up conversion tracking on the theme.liquid and checkout page as instructions.
Picture 1: Campaign setting
Picture2: Ads tools setting
Picture4: Theme.liquid code. There is a question：What the marked ads number is automaticlly generated, but it's different than my ads number. is it a problem? Is the code position right?
Picture5: setting on shopify check out
where is wrong setting? or need other setting? Please give me advice！ Thanks
