I must add here that most people play lebensohl after a weak 2 double.
In the version that I and my P play 3♠ would deny a ♠ stopper and confirm 4 card of ♥and Game Force.
So lebensohl was a liability here?
There is a lot to be said for the showing/denying a stopper when playing Lebensohl after a NT opening. Opener has some expectation of having a stopper, so checking for this is useful.
However, the same considerations do not apply when playing Lebensohl over a weak 2. Here there is no expectation that the doubler has a stopper, and no real expectation that 3NT is the default contract. It's better for either player to only bid 3NT when they hold the stopper, both for positional reasons and because it provides other options in the bidding.
There are a number of alternatives that make better use of the bids. My default suggestion when discussing this with a new partner is that using 2NT shows 4 of the other major. So 2NT then cue = 4 hearts and game values; 2NT then 3NT = 4 hearts and a spade stopper, and 2NT then 3H = invitational with exactly 4 hearts. Now the direct bids can show GF with 0-3 or 5+ hearts, to play without 4 hearts (but with a spade stopper), and 5+ hearts and invitational, respectively. Over either of the cue bids, partner can bid 3NT if they don't have a fit and have a spade stopper.
So yes, IMO the way you are playing Lebensohl here is a liability.
