Coefplot plotting same (name) estimate from different OLS models across three years in a single graph

Question

Using coefplot in Stata, I am unable to plot the same estimate from different models across three years without having the estimates bunch up into a single year's plot region.

The steps in my code are in the order below:

Estimate the slope coefficients with reghdfe and store them.

Prepare the estimates for esttab with estfe and export tables.

Only plot the estimated coefficients on the independent variable for three dependent variables (dv). Each dv has 4 models. Each model is estimated for 3 years. Total 12 estimated coefficients for each of the 3 outcome (subgraph). The models start with the word: reg (for bivariate); C (with controls); P (bivariate placebo sample); C_P( placebo sample with controls).

Unexpected graph output (attached): while the 3 subgraphs in the graph indicate the 3 years beside the Y axis but the estimates are bunched up in 1 year's plot region in each of the subgraphs rather than plotted neatly across all 3 years. The labels for each individual year are also overlapping with one another.

I think the problem lies somewhere in my use of coefplot syntax, specifically the use of parentheses, in calling the same estimated coefficient from several models either after coefplot or with group option as I do get the desired plot when I don't plot the 3 years or plot the years horizontally. I am unable to neatly plot the years vertically however.
