Supposed episode of a series that doesn't exist

Hi, I'll explain. Estudio 1 (tt0415421) was a spanish TV programme of theatrical plays on television broadcasts. In the episodes list appear a supposed episode which was aired on January 02 1981, "Las novias de Travolta" (tt32768900), starring Carla Hidalgo (b. 1973) and Beatriz Rico (b. 1970). "Las novias de Travolta" was a theatrical played starred by that two actresses (and other two) which actually was performed in theatres starting on October 06 2011 (30 years later of the supposed TV emision). I was checking in the TV newspaper archive looking for evidences to prove that at least that play was aired on TV (although the supposed date would be wrong), but I didn't find anything. https://zonaretiro.com/teatro/novias-travolta-teatro-arenal/ https://www.bekia.es/celebrities/fotos/galerias/famosos-estreno-teatras-novias-travolta/carla-hidalgo-beatriz-rico-elena-martin-isabel-pintor-novias-travolta/
