I have the same problem. Did you ever find a solution that doesn't involve uninstalling the software?
My device is a LG Leon LTE from MetroPCS, with Android 5.1.1 installed. I also have other symptoms to add to this issue.
On profiles where ABS is set to disable the phone's wi-fi, it does exactly what the OP says it does. In addition, if I manually turn off the Wi-Fi, ABS turns it back on within 1-2 minutes, even if the active profile is set to disable the wi-fi. On profiles where wi-fi is set to on, or optimized, ABS repeatedly disrupts my wi-fi connection, causing my phone to either switch to another saved wi-fi connection, (disrupting that one in the same manner within a few minutes), or switch to mobile data. Usually the message I get from my phone when this happens is that my wi-fi connection has no internet.
Disabling, or uninstalling the app are the only solutions I've found that work so far.
