Lidl Silvercrest 368308_2010 thermostat not showing week schedule values in frontend

[Element2]

What happened?

When using the Z2M frontend the week schedule settings are not showing values on the 'Exposes' tab. The temp slider is showing 0 on all days for all settings, also the hour and minutes are not filled in. If the blue refresh button in front of a slider (for example monday) is clicked, a red popup message appears with 'No convertor available for 'get' 'monday' [object Object]. The slider and hour and minute settings do work when setting a value, but the values are not kept when refreshing the page.
The values of the week schedule can be seen in the 'State' tab

What did you expect to happen?

I expected to see all the week schedule values of temp, hours and minutes for all the settings per day being displayed as set in the schedule on the thermostat.

How to reproduce it (minimal and precise)

Pair a 368308_2010 Lidl Silvercrest thermostat, go to the frontend and on the 'Devices' tab select the paired thermostat. Then go to the 'Exposes' tab and scroll down to the week schedule.

Same problem here. When refreshing it shows: cannot get object Monday.

Same here. The problem exists since 1.27.1. Version 1.27.0 works as expected.
