This could indicate there is a flaw in LCDM and that we might have to consider an alternative rather than the simple cosmological constant (Note 1).
The favorite explanation is this cosmological constant.

Thereafter Lemaitre (1927) showed that the universe, having the positive cosmological constant [LAMBDA], turns out to be exponentially expanding in time.
Although this model is asymptotically anti-de Sitter, by assuming a small-enough cosmological constant, the manifold is sufficiently close to flat in the vicinity of the blackplane for this prescription to be valid.
In his general theory of relativity, Einstein introduced a cosmological constant in an effort to force a static universe from his equations.
Influence of The Cosmological Constant in the Angle of Deflection of a Gravitational Lens
This is in contrast to the traditional static vacuum energy or cosmological constant.
For example, Albert Einstein's theory of general relativity introduced the notion of a cosmological constant to explain what he assumed was a static universe, which was the prevailing scientific view at the time.
Einstein's Field equation with cosmological constant [lambda] is given by
The 60 papers examine such topics as cold compressed baryonic matter with hidden local symmetry and holography, topological and curvature effects in a multi-fermion interaction model, continuum superpartners from supersymmetric unparticles, new regularization in extra dimensional model and renormalization group flow of the cosmological constant, and critical behaviors of sigma-mode and pion in holographic superconductors.
Abstract: The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) aims to make a direct detection of dark energy at z~3, in the case that it is a cosmological constant.
This discovery has brought into being the concept of dark energy, which may be linked to Einstein's cosmological constant.
