[BUG] Layer Inconsistency After Print Resume

[OwenD30]

Firmware Version: v1.4.6 stable (davidramiro)
Slicer: Cura
Printer Model: Mega-S
Hardware Modifications: None, I'm using the stock drivers but I calibrated the extruder

When I was printing an XYZ calibration cube, I paused the print to check the infill and then resumed. The first layer after resuming was slightly higher than it should've been, creating a line that runs all around the print. I am having problems with slight overextrusion, but that shouldn't have caused the layer inconsistency.

To replicate:

1. Start a print
2. Pause it (I paused mine about a half centimeter up)
3. Resume it again

I expected the layer to look almost the same as the others. Is there anything I can calibrate or is this a bug? I have no M503 output (the results are all in the print).
