Input this command into command block:
/setblock ~ ~1 ~ wall_sign 5 replace {Text1: "{\"text\": \"hello\"}"}
Exit world.
Enter world and text will have disappeared.
Happens with both standing signs and wall signs.
Placing a sign without using /setblock, is not affected by this.

Each line must be filled, and each line must be JSON.
You can use one of those commands as template :
/setblock ~ ~1 ~ minecraft:standing_sign 0 _ {Text1:"{\"text\":\"\"}",Text2:"{\"text\":\"\"}",Text3:"{\"text\":\"\"}",Text4:"{\"text\":\"\"}"}
/setblock ~ ~1 ~ minecraft:standing_sign 0 _ {Text1:"[\"\"]",Text2:"[\"\"]",Text3:"[\"\"]",Text4:"[\"\"]"}
