Remove the Ruler (
https://terraria.gamepedia.com/Ruler) from your inventory, or if you have the The grand Design (
https://terraria.gamepedia.com/The_Grand_Design), open/disable parts of it as told in the wiki:
"The Grand Design can be used at any part of the screen, regardless of block placement range. When pressing ⚷ Open / Activate with the tool, a small menu will pop up at the cursor's position with six different buttons in a radial pattern. The outside buttons can be used to select which wire colors (including Actuators) can be interacted with, and the middle button will toggle between placing or harvesting the designated wires. In addition, as long as The Grand Design is anywhere in the inventory, seven buttons will appear on the left-hand side of the screen, controlling whether to display the ruler or not and whether to highlight actuators and/or the four different colors of wires.
