Artillery + Main Cannon Issue

Am I the only one who, since the previous big update, has had an inconsistent problem with use of artillery.

Here’s what happens:
I use the 5 key (default) to open my artillery map and when I click LMB to set coordinates for the volley of artillery, it treats it as 2 inputs and fires my main cannon. I know for a fact I have not clicked twice and it happened even after deep-cleaning my mouse.

The issue has revealed my position on several occasions and caught me dead to rights. I fear the thought of needing to download the game again and want to see if anyone else is experiencing the issue. Again it doesn’t happen on every Artillery use
