Can't use delete key in CLI of Cisco SG300

Hey fellow /r networkers..

I have a bunch of new Cisco Small Business SG300-52 and -28 switches that we are rolling out at my organization. I noticed I am having an issue where I cannot use the delete key within the CLI. Normally these are set at a default baud rate of 115200, but I updated to default to 9600 and still no dice. I know my copy of putty is fine because the delete key works on other Catalyst devices I console into, but this IOS is a little bit different than the Catalyst. Any idea what gives? Probably am overlooking something easy..thanks in advance!
