Hello.
You'll need to set the Bid->Amount as shown in this AddKeywords example:
https://msdn.microsoft.com/en-US/library/bing-ads-keywords-php-code-example.aspx 
$keywords = array();
$keyword = new Keyword();
$keyword->Bid = new Bid();
$keyword->Bid->Amount = 0.47;
$keyword->Param2 = "10% Off";
$keyword->MatchType = MatchType::Phrase;
$keyword->Text = "Brand-A Gloves";
$keywords[] = $keyword;
If it still doesn't work for you please feel free to
escalate to support with the SOAP request and response i.e. place this code immediately after your call to UpdateKeywords:
print "\nLast SOAP request/response:\n";
print $proxy->GetWsdl() . "\n";
print $proxy->GetService()->__getLastRequest()."\n";
print $proxy->GetService()->__getLastResponse()."\n";
I hope this helps!
