bug: pipette.starting_tip does not work correctly with api version 2.14

[sannji1117]

Overview

Using pipette.starting_tip with api version 2.14, for example, when I write pipette.starting_tip = tip_rack_1.well('C3') in my protocol, the first pipette pick_up_tip() picks up C3 as expected, but the next pipette.pick_up_tip() picks up A1 instead of D3, and the third and subsequent times, B1, C1, and so on.

Steps to reproduce

No response

Current behavior

No response

Expected behavior

Using pipette.starting_tip with api version 2.14, for example, when I write pipette.starting_tip = tip_rack_1.well('C3') in my protocol, the first pipette .pick_up_tip() picks up C3, and then the robot should pick up D3, E3, and so on, instead of A1, B1.

Operating system

None

System and robot setup or anything else?

Changing to api version 2.13 eliminates this unexpected pickup chip behavior. So I think this unexpected move of OT-2R is originated in the api 2.14 bug error.
