You would need to use a newer VIAL update then. Please use that. There are no official QMK firmwares with older versions.

So far, the same error occurs even with the latest Vial firmware. :(
Could you please allow merging of v2 definitions?
Last time, I solved this problem by allowing you to add v2 definition.

Ah it uses the old version... :/ id prefer not to have overlap there due to potential issues for both yourself and your customers. That was an exception. We really want to move away from older things with newer nicer macros (with delays) and encoders in V3.
