# Can't see all my edits

I am sure that I edited the following answer

How may we prove that $\int_{0}^{\infty}{\sinh^2(x)-x\over \cosh^3(x)}\cdot{4x\over e^x}\mathrm dx=2-\zeta(2)?$

at least three times but in the editing history

It says that I only edited only once. Actually before the the last edit the (edited) link disappeared.

I had answers where the editing shows more than one edit. Am I amissing something or it doesn't show small edits ?
