ARDL bug in EViews 14 ?

Dear EViews team,
Using the ARDL procedure in EViews 14, the estimation runs normally and the cointegration equation is correctly estimated, but all ARDL coefficients are reported as zero (t = 0, p = 1) !
Best regards

for exemple :
Dependent Variable: RATE_10Y
Method: ARDL
Date: 02/09/26 Time: 00:04
Sample: 2003M04 2025M09
Included observations: 270
Lag selection: Automatic (deplags=12, reglags=0)
Selected model: ARDL(3,0,0) using AIC (12 models evaluated)
HAC standard errors & covariance (Bartlett kernel, Newey-West fixed
bandwidth = 5.0000)

Variable Coefficient Std. Error t-Statistic Prob.*

Funny case: Estimation - Option - Coefficient name (return C instead of ardl). All will be fine :P
