Mobile editor V1.3.0 Bug?

Hello, with the version just downloaded Mobile editor V1.3.0, a popup appears that cannot be closed, then only the Edit preset section works, all the others as shown in the photo do not display anything.

the IOS version I have installed is 13.3.1 on Iphone 7 Plus. I do not intend to update my system to 15.5 to avoid malfunctions on other installed Apps.
