3CX Logo keeps coming back

[GH-JD]

We have Yealink T46S's i have set a logo the correct size and everything in the management console, but they 3cx one comes back then ours comes back just keeps swap between the two.

Any Idea's?

I have seen that you may need to create a copy template file, but how would i go about using this custom one when the phones are behind an SBC and they auto provision?

Regards

Matt
