ACL Adding a access-group to a interface not selectable ??

[JayWM]

Hello,  I believe this to be a CLI command line bug.

I have done this before successfully but can't remember how you do this 

Config:

ip access-list extended 100
remark Block_CapWap
sequence 10 deny udp any any eq 5246
sequence 20 deny udp any any eq 5247
sequence 30 permit ip any any
!

BUT! 

When I try and add it to the Inf it doesn't add it but drops me into building the ACL

See:

(config)#interface ethernet 2/1/3

config-if-e1000-2/1/3)#ip access-list extended Block_CapWap
SW(config-ext-nacl)#

****Here you can see it applied to a working interface.***

ip access-list extended 100
remark Block_CapWap
sequence 10 deny udp any any eq 5246
sequence 20 deny udp any any eq 5247
sequence 30 permit ip any any

Show Int e 1/1/23

interface ethernet 1/1/23
port-name WiFi CGP_Ticket_EX~
loop-detection
dual-mode 750
ip access-group Block_CapWap in
spanning-tree 802-1w admin-edge-port
inline power power-by-class 4
stp-bpdu-guard
trust dscp
sflow forwarding
sflow sample 4096
snmp-server enable traps mac-notification

Thx
