plotting a graph with 2 x-axis in a tile plot

I have created some code to create a graph with two x-axis. I would like to display this is in a tile plot, but when I try to create the next tile it overwrites the data of the first.
How can I create a new tile which doesn't affect the first?

We cannot run your code due to the missing input data. So we cannot check, in which line the described effect happens. But you can do this useing the debugger. Step through the code line by line and find out, where the overwriting happens. Maybe you have to create a new axes explicitly.

If this does not work, please post a minimal working example using some rand data as input.

I've found mysterious lines:

t=tiledlayout(3,2)
ax1=axes(t);
...
ax3=nexttile   % ???
ax3=axes(t);
...
ax3=axes(t);   % ??? again?
ax4=axes
