@jim.schmitz and @andshe I tried to reproduce this with 64 bit Toad 14.0 but didn't have any luck. Do you have default values in the auto-replace list or have you added some?
@andshe Would you mind trying it in beta to see if it is fixed there with auto replace enabled? You can get it here.
Leave 14.0 installed if you install the beta. The beta won't run without latest official version also present. The beta will import your 14.0 settings but keep its own copy of settings after that.
