LaTeX forum ⇒ LyX ⇒ Language problem for float object

[faca]

Hello, I wrote a document (book style) by lyx.
I set
Document->Setting->Language->Language in English, and for example I get "Chapter, Section", etc in English, but in the caption of float objects (both figures and tables), I get the italian word (i.e. Figura and Tabella).
I also wrote in the preable

\usepackage[english]{babel}

Moreover, looking the source code, I notice

\begin{center}
\begin{table}[tbph]
\begin{centering}
\begin{tabular}{cccc}
\hline 
\selectlanguage{english}%
Target material\selectlanguage{italian}%
 & Thickness $\unit{\left(mm\right)}$ & \selectlanguage{english}%
\ac{MPV}\foreignlanguage{italian}{ $\unit{\left(MeV\right)}$ first
target}\selectlanguage{italian}%
 & \selectlanguage{english}%
\ac{MPV} \foreignlanguage{italian}{$\unit{\left(MeV\right)}$ second
target}\selectlanguage{italian}%
\tabularnewline

you see...there are those switches

\selectlanguage

,

\foreignlanguage

...maybe this is the prolem, but I don't know how to fix it
Does anyone know how to fix it, please?

All these language changes in the tabular are nonsense. You should avoid them.
